Python将目录中的文件作为函数参数循环

Question

In my python scirpt I have a function func01 that takes a pdf file as argument:

func01("pdf1.pdf")

This works and gives me the expected output.

Now I want to perform func01 on all files in my directory. I tried this:

import glob, os
os.chdir("/articles")
for file in glob.glob("*.pdf"):
  myoutput = func01(file)

... but this does not work: TypeError: 'str' object is not callable

Searching on SO, I re-wrote my script to:

for file in glob.glob("*.pdf"):
  path_  = os.path.realpath(file)
  myputput = func01(path_)

So what I want is to use each file from the loop as input for my function. What am I missing in my code?

Answer 1

Your error message

TypeError: 'str' object is not callable

implies that somewhere along the line you're doing "some string"(...) . In the code you posted you only have a few function calls.

• os.chdir("/articles")
• glob.glob("*.pdf")
• myoutput = func01(file)

So either os.chdir , glob.glob , or func01 have been overwritten to be a string.
