Python: Converting file to base64 encoding

Question

This is my code:

import base64

with open('/Users/Bob/test.txt') as f:
    encoded = base64.b64encode(f.readlines())
    print(encoded)

I've based it on the base64 documentation. However, when I try running it with Python 2.7.1 and Python 3.2.2 I get the error:

    import base64
  File "/Users/Bob/test.txt'", line 4, in <module>
    encoded = base64.b64encode(f.readlines())
AttributeError: 'module' object has no attribute 'b64encode'

Why can't the b64encode attribute be found?

You have a script named base64.py which is shadowing the stdlib module. Rename it.

Wow, that was super quick! How did you figure out the problem? I did indeed call the file base64.py.

You're not the first to do this.

@IgnacioVazquez-Abrams and as evidenced by the continued upvotes, not the last one to do this either :)

I would also like to note that the "f.readlines()" should be "f.read()" as the encoder needs a string. (Tested on mine and had the issue.)

@Yetti definitely not the last. 7 years later I keep making the same mistakes sometimes
