| Using .strip() on windows leads to the first and last character of a word being deleted. Magenta.zip becomes agenta.zi |

| Please provide the exact code to duplicate the problem. I suspect this is a problem with your code, not with str.strip and not with Windows. |

| I cannot run that example on my computer. Please reduce this to a single line of code, with no imports, that calls .strip() and shows your problem. Ideally you will just use constants, and not computed strings. Something like: >>> 'magenta.zip'.strip('pizamn') 'genta.' And also, show that exact same line of code executed on both platforms. That said, the problem is likely in your usage of .strip(). Please re-read the documentation: it does not remove substrings from a given string, it removes any of the given characters from the beginning and end of the string. So, this is correct: >>> 'magenta.zip'.strip('pm') 'agenta.zi' You're probably seeing some difference due to upper or lower case filenames on the two platforms. |

| I have read the documentation. It didn't function near what I thought it did. I've never heard it stripping front and back characters in tutorials. I solely admit I was wrong in assuming its function. On Sat, Mar 30, 2019, 3:35 PM Eric V. Smith <report@bugs.python.org> wrote: > > Eric V.
