On Python 3.9 and newer you can use the removeprefix and removesuffix methods to remove an entire substring from either side of the string: url = 'abcdc.com' url.removesuffix ('.com') # Returns 'abcdc' url.removeprefix ('abcdc.') # Returns 'com'. The relevant Python Enhancement Proposal is PEP-616.
In the particular case where you know the number of positions that you want to remove from the dataframe column, you can use string indexing inside a lambda function to get rid of that parts: Last character: data['result'] = data['result'].map(lambda x: str(x)[:-1]) First two characters: data['result'] = data['result'].map(lambda x: str(x)[2:])
26 lip 2024 · String slicing in Python is about obtaining a sub-string from the given string by slicing it respectively from start to end.

31 sty 2024 · This tutorial will walk you through three primary methods for trimming strings in Python: .strip(), .lstrip(), and .rstrip(), and will cover specific use cases to demonstrate their versatility and utility in real-world scenarios.
27 lip 2021 · Python provides different ways and methods to generate a substring, to check if a substring is present, to get the index of a substring, and more. You can extract a substring from a string by slicing with indices that get your substring as follows: string [start:stop:step] start - The starting index of the substring.
Python provides string methods that allows us to chop a string up according to delimiters that we can specify. In other words, we can tell Python to look for a certain substring within our target string, and split the target string up around that sub-string.
Remember that when you use .split(), you call it on the string or character you want to split on. The opposite operation is .join(), so you call it on the string or character you want to use to join your iterable of strings together: Python. >>> strings = ['do', 're', 'mi'] >>> ','.join(strings) 'do,re,mi'.
