I used both global , nonlocal but both throws different error
throws this error
nonlocal test_var ^
SyntaxError: invalid syntax

I think that this boils down to this:
You should also understand difference between reference and assignment:
When you reference a variable in an expression, the Python interpreter will traverse the scope to resolve the reference in following order:
- current function’s scope
- any enclosing scopes (like containing functions)
- scope of the module that contains the code (global scope)
- built-in scope (that contains functions like int and abs)
If Python doesn't find defined variable with the referenced name, then a NameError exception is raised.
Assigning a value to a variable works differently. If the variable is already defined in the current scope, then it will just take on the new value. If the variable doesn’t exist in the current scope, then Python treats the assignment as a variable definition. The scope of the newly defined variable is the function that contains the assignment.

Metaphlan3 running problem UnboundLocalError
I had an error when running metaphlan3 in the first step. My command is “metaphlan SRR7563636_1.fastq,SRR7563636_2.fastq --input_type fastq -s sams/SRR7563636.sam.bz2 --bowtie2out bowtie2/SRR7563636.bowtie2.bz2 -o profiles/SRR7563636_profile.tsv”.
But it reported, Downloading https://www.dropbox.com/sh/7qze7m7g9fe2xjg/AAA4XDP85WHon_eHvztxkamTa/file_list.txt?dl=1

I can’t download the database by dropbox on our public server. Is there any way to solve or bypass this problem? For example, could I download the file and deposit it under some directory? Thank you so much!
Yes, you can download the database from Zenodo https://zenodo.org/record/3957592#.XzYjcB7RZ-E
and run MetaPhlan with the -x mpa_v30_CHOCOPhlAn_201901 parameter. You probably should update your installation, the latest version (3.0.2) automatically retrieves the database from Zenodo if Dropbox fails.
Thank you so much!!! I will try it.
Hi, Sorry to bother you. I download the database and deposited it under the path “/gpfs/data/lilab/home/zhoub03/software/metaphlan3_database/mpa_v30_CHOCOPhlAn_201901”. I have tried to specify the database by using
- “metaphlan SRR7563636_1.fastq,SRR7563636_2.fastq --input_type fastq -s sams/SRR7563636.sam.bz2 –bowtie2db /gpfs/data/lilab/home/zhoub03/software/metaphlan3_database/mpa_v30_CHOCOPhlAn_201901 -x mpa_v30_CHOCOPhlAn_201901 --bowtie2out bowtie2/SRR7563636.bowtie2.bz2 -o profiles/SRR7563636_profile.tsv”
- “metaphlan SRR7563636_1.fastq,SRR7563636_2.fastq --input_type fastq -s sams/SRR7563636.sam.bz2 -x mpa_v30_CHOCOPhlAn_201901 --bowtie2out bowtie2/SRR7563636.bowtie2.bz2 -o profiles/SRR7563636_profile.tsv”
- “metaphlan SRR7563636_1.fastq,SRR7563636_2.fastq --input_type fastq -s sams/SRR7563636.sam.bz2 –bowtie2db /gpfs/data/lilab/home/zhoub03/software/metaphlan3_database/mpa_v30_CHOCOPhlAn_201901 --bowtie2out bowtie2/SRR7563636.bowtie2.bz2 -o profiles/SRR7563636_profile.tsv”
However, none of these commands worked. The tutorial just said, “Just download the .tar, .md5, and the mpa_latest files and place them in the metaphlan_databases folder .” So, where should I deposit the database? How can I let the metaphlan know where to find the database? Thank you so much!
Have you built the database with bowtie2-build ?
Yes, I have built the database under “/gpfs/data/lilab/home/zhoub03/software/metaphlan3_database/mpa_v30_CHOCOPhlAn_201901” and obtained “mpa_v30_CHOCOPhlAn_201901.1.bt2”. But when I ran “metaphlan SRR7563636_1.fastq,SRR7563636_2.fastq --input_type fastq -s sams/SRR7563636.sam.bz2 –bowtie2db /gpfs/data/lilab/home/zhoub03/software/metaphlan3_database/mpa_v30_CHOCOPhlAn_201901 --index mpa_v30_CHOCOPhlAn_201901 --bowtie2out bowtie2/SRR7563636.bowtie2.bz2 -o profiles/SRR7563636_profile.tsv”, it still reported the following error.
Downloading … Warning: Unable to download No MetaPhlAn BowTie2 database found (–index option)! Expecting location /gpfs/data/lilab/home/zhoub03/software/metaphlan3_database/mpa_v30_CHOCOPhlAn_201901/mpa_v30_CHOCOPhlAn_201901 Exiting…
Due to some internet safety issues, the metaphlan can’t automatically download the database. So where should I deposit the built database? How should I name the folder that contains the database? Thank you so much for your kindly help!
Is it the only file you got? You should have six .bt2 files in the “/gpfs/data/lilab/home/zhoub03/software/metaphlan3_database/mpa_v30_CHOCOPhlAn_201901” folder
Thank you so much! The bowtie reference was not completely generated. Now, this problem has been solved.

UnboundLocalError: local variable ‘trialList’ referenced before assignment
OS (e.g. Win10): macOS13.2.1 PsychoPy version (e.g. 1.84.x): 2022.2.5 What are you trying to achieve?: upload a csv making it a condition for trials
What did you try to make it work?: I’ve reload PsychoPy version from 2023 to 2022, and my friends’ mac works with the 2022 version. Also, I checked my csv file to make sure it’s right for PsychoPy.
What specifically went wrong when you tried that?: Traceback (most recent call last): File “/Applications/PsychoPy.app/Contents/Resources/lib/python3.8/psychopy/app/builder/dialogs/ init .py”, line 1531, in onBrowseTrialsFile File “/Applications/PsychoPy.app/Contents/Resources/lib/python3.8/psychopy/data/utils.py”, line 466, in importConditions UnboundLocalError: local variable ‘trialList’ referenced before assignment
Check your conditions file for spaces in the column names
Thanks for your answering, I’ve checked it. Below is my file, hope you can find the error I get. conditions_1.csv (139 Bytes)
I’ve also tried to use commas rather than semicolons, it causes the same error message.
Sorry for the delay. I’ve just checked our bug fixes and I think this is due to one of your columns being called corrAns, which accidentally got used by the developers for something else.
It should be fixed if your change your column to something else (e.g. corrAnswer) or you could try the 2024.1.0 release which is now available to download from Releases · psychopy/psychopy · GitHub
However, it may be something else, such as:
or maybe you have used word or congruent as an object name as well as a variable

UnboundLocalError: local variable referenced before assignment
I have following simple function to get percent values for different cover types from a raster. It gives me following error: UnboundLocalError: local variable 'a' referenced before assignment
which isn't clear to me. Any suggestions?

- 1 Because if row.getValue("Value") == 1 might be false and so a never gets assigned. – Nathan W Commented May 20, 2013 at 2:39
- It has value and do gets assigned. I checked it in arcmap interactive python window but can't get it to work in a stand alone script. – Ibe Commented May 20, 2013 at 2:44
- 1 your loop will also only give you the values of the last loop iteration as you are returning out of the loop and not doing anything with each value. – Nathan W Commented May 20, 2013 at 2:49
- You could use 3 x elif and an else to see if any values other than 1-4 are encountered. – PolyGeo ♦ Commented May 20, 2013 at 3:44
- I tried that way as well but still hung up with error. – Ibe Commented May 20, 2013 at 4:15
This error is pretty much explained here and it helped me to get assignments and return values for all variables.

Unboundlocalerror: local variable referenced before assignment occurs when a variable is used before its created. Python does not have the concept of variable declarations. Python does not have the concept of variable declarations.
Avoid Reassignment of Global Variables. Below, code calculates a new value (local_var) based on the global variable and then prints both the local and global variables separately.It demonstrates that the global variable is accessed directly without being reassigned within the function.
UnboundLocalError: local variable referenced before assignment. Example #1: Accessing a Local Variable. Solution #1: Passing Parameters to the Function. Solution #2: Use Global Keyword. Example #2: Function with if-elif statements. Solution #1: Include else statement. Solution #2: Use global keyword. Summary.
The Python "UnboundLocalError: Local variable referenced before assignment" occurs when we reference a local variable before assigning a value to it in a function. To solve the error, mark the variable as global in the function definition, e.g. global my_var .
The UnboundLocalError: local variable 'x' referenced before assignment occurs when you reference a variable inside a function before declaring that variable. To resolve this error, you need to use a different variable name when referencing the existing variable, or you can also specify a parameter for the function. I hope this tutorial is useful.

In order for you to modify test1 while inside a function you will need to do define test1 as a global variable, for example: test1 = 0. def test_func(): global test1. test1 += 1. test_func() However, if you only need to read the global variable you can print it without using the keyword global, like so: test1 = 0.
