Lastly, an important application of strings is thesplitmethod, which returns a list of all the words in the initial string and it automatically splits by any white space. It can optionally take a parameter and split the strings by another character, like a comma or a dot 4. Formatting str...
a nice string representation of the object. | If the argument is a string, the return value is the same object. | | Method resolution order: | str | basestring | object | | Methods defined here: | | __add__(...) | x.__add__(y) <==> x+y | | __contains__(...) | x...
maxsplit − Optional. Number of splits to do; default is -1 which splits all the items. str.rsplit([sep[, maxsplit]]) Thestr.rsplitreturns a list of the words in the string, separated by the delimiter string (starting from right). Python split examples In the following examples, ...

最近在解析命令行参数的时候碰到python字符分割的问题,python中字符串分割默认都是在空格,但是我的参数中可能某个参数带有空格符,同时有双引号包围。 最近的python中引入了支持正则分割的shlex模块,他能很好的处理空格符的问题。如下: >>>importshlex>>>shlex.split('this is "a test"')['this','is','a test...
If sep is not specified or is None, any whitespace string is a separator and empty strings are removed from the result. """ return [] 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. #!/usr/bin/python str = "Line1-abcdef \nLine2-abc \nLine4-abcd"; print str.split( ); print...
When a function is too long or complicated, split it into simpler functions for readability. Use Descriptive Names: Names of functions should describe the action they perform, making the code more readable. Avoid Global Variables: Using too many globals can complicate debugging. Pass values in as...
