After run the script:

>>>IndentationError: unexpected indent

Anyone can help me to solve the problem?

Answer 1

In python you must properly indent statements after ':'. Change

with open('c:/logs/kellyrate.txt','a') as kellyrate:
kellyrate.write(container0 + "\n")

to

with open('c:/logs/kellyrate.txt','a') as kellyrate:
    kellyrate.write(container0 + "\n")

Answer 2

This error message...

IndentationError: unexpected indent

...implies that there were indentation errors in your code block.

Python Indentation

Indentation refers to the spaces at the beginning of a code line. Python uses indentation to indicate a block of code.

This usecase

In your program, the line of code:

kellyrate.write(container0 + "\n")

acts as a block of code which will be iterated for each line in c:/logs/kellyrate.txt . So you need to indent this line of code either by:

• tab character
• blank space characters

So your effective code block will be:

with open('c:/logs/kellyrate.txt','a') as kellyrate:
    kellyrate.write(container0 + "\n")
