In the example, we spit the string into a list of words withre.spit. The words can be separated a comma or a semicolon and multiple white spaces. $ ./reg_split.py ['sky', 'club', 'cpu', 'cloud', 'war', 'pot', 'rock', 'water'] Python word frequency In the following exampl...
我假设您总是使用以下格式的字符串。 your_string = '<FIRST_PART(CAN CONTAIN SPACES)> <SECOND_PART(WITHOUT SPACES)> <THIRD_PART(WITHOUT SPACES)>' 如果是,您可以使用rsplit(maxsplit=2)获得所需的输出。 >>> string = 'ESO 12-4 356.0648792 -80.1770250' >>> string.rsplit(maxsplit=2) ['ESO ...
You can split a string on multiple delimiters in Python using many ways, for example, by using there.split(),re.findall(),re.split(),translate()&maketrans(),replace(), andsplit()functions. In this article, I will explain how to split a string on multiple delimiters by using all these...

It even considers the spaces. max() Function in Python The max() function returns the largest item in an iterable (like a list, or tuple) or among multiple numbers given as arguments. Example 1: Python 1 2 3 4 # Finding the maximum value in a list numbers = [10, 25, 18, 40...
There.split()function takes a regular expression pattern as its first argument and the target string as its second argument. You can use this function to split strings based on complex criteria, such as multiple, inconsistently used delimiters: ...
