Running a Python Script in Terminal

Question

I am new to Python. Right now I have created a file, "testing.py" in an XCode text editor. It runs a simple program, and I want to be able to run it in the Terminal. Up to now I have just been opening the Terminal, typing "python", and retyping the same code over and over.

Also, I tried typing "python testing.py" in the Terminal, and it gave me an error:

File "testing.py", line 22
break
SyntaxError: 'break' outside loop

The code snippet that caused an error was:

with open("truth.txt") as f:
    while True:
        i = f.read(1)
        if not i:
            break
        bitstring += bin(ord(i))[2:].zfill(8)

Any suggestions?

Answer 1

This is not an answer why SyntaxError: 'break' outside loop raised.

But your code can be improved as

>>> with open("truth.txt") as f:
...     for i in iter(lambda:f.read(1), ''):
...         bitstring += bin(ord(i))[2:].zfill(8)

You done need to use break anymore.
