Try this: import aststring = "['a', 'b', 'a e']['de']['a']['a']"string = string.replace("]", "],")list_ = list(ast.literal_eval(string))print(list_) output: [['a', 'b', 'a e'], ['de'], ['a'], ['a']] 请记住,如果列表中的某个项是]字符,则此操作将失败...
Different Methods for Converting a String to a List 1. Using split() The split() method is the most common way to convert a string into a list by breaking it at a specified delimiter. string = "apple,banana,cherry" list_of_fruits = string.split(",") print(list_of_fruits) # Output...

It will give a list of symbols, unlike the above example, 4. Using string slicing You can use slicing to convert a string into a list. It iterates data according to our needs. Colon(:) is used to cut anything in Python. Example: ...
fill_value :scalar, default None Value to replace missing values with margins : boolean, default False Add all row / columns (e.g. for subtotal / grand totals) dropna :boolean, default True Do not include columns whose entries are all NaN ...
# Program to convert string to integers list # Declare a string str1 = "12345" # Print string print("Original string (str1): ", str1) # List to store integers int_list = [] # Iterate string, convert characters to # integers, and append into the list for ch in str1: int_list....
安装过程中有一个很重要的步骤,如下图:"Add python.exe to Path"这里默认是打叉关闭的,请务必记住点开它并选择"Entire feature will be installed on local hard drive.'',它会自动帮你设置好环境变量,(也就是说你以后打开CMD运行Python脚本时,你可以在任意盘符和文件夹下直接输入"python xxx.py"来运行脚本...
