You may only want to match occurrences of your substring followed by punctuation, or identify words that contain the substring plus other letters, such as "secretly".For such cases that require more involved string matching, you can use regular expressions, or regex, with Python’s re module....
if (str.__contains__(string, my_substring)): print(‘String contains substring!’) else: print(‘String does not contain substring’) The first argument is the string you are searching, and the second is the substring you are looking for. It also returns a Boolean. But these methods are...
str.format(format_string, *args, **kwargs) Perform a string formatting operation. The format_string argument can contain literal text or replacement fields delimited by braces {}. Each replacement field contains either the numeric index of a positional argument, or the name of a keyword argument...
If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace. Consequently, splitting an empty...

sys.path 即 sys.__dict__['path'] 是一个 PyListObject 对象,包含了一组PyStringObject 对象,每一个对象是一个module 的搜索路径。 第三方库路径的添加是 lib/site.py 完成的,在site.py 中完成两个动作: 1. 将 site-packages 路径加入到 sys.path 中。
