Excuse the title. This is just a very strange error I am getting. When I try to pull two xls files and one csv file into a dataframe I get this error:
FileNotFoundError: [Errno 2] No such file or directory: '.\\pa-dirty-price-crawler\\goldman_folder\\Trade_Detail_GSCO_GREAT_AJAX_OPERATING_PARTNERSHIP_L.P._COB08_Apr_2020_19_1586111993954.xls'
That error occurs when I do this:
nomura = get_nomura_df_by_date(start_date)
jpm = get_jpm_df_by_date(start_date)
gs = get_goldman_df_by_date(start_date)
Now if I comment out either nomura or jpm then there is no error at all. In other words if I do this
# nomura = get_nomura_df_by_date(start_date)
jpm = get_jpm_df_by_date(start_date)
gs = get_goldman_df_by_date(start_date)
Then I receive no error at all which is weird. The xls and csv files are all in separate folders in my workspace, i.e., I have one folder for goldman, one for nomura, and one for jpm.
Here is the entire code:

Note that I took out my name and put "usr_name" in the post. I am baffled by this error and I have no idea why it's breaking.
EDIT:
I am starting to identify the issue. When I just call the function to get the zip folders then the code runs fine, the issue occurs when I unzip the folders when I am trying to get all the dataframes. Perhaps that may add some details that you guys could point out for a solution.
