hello = "This is a rather long string containing\n\ several lines of text just as you would do in C.\n\ Note that whitespace at the beginning of the line is\ significant." print(hello) --- This is a rather long string containing several lines of text just as you would do in C....
Split the string at the first occurrence of sep, and return a 3-tuple containing the part before the separator, the separator itself, and the part after the separator. If the separator is not found, return a 3-tuple containing the string itself, followed by two empty strings. New in vers...
When Python runs the f-string, it builds an expression-like string containing the variable’s name, the equal sign, and the variable’s current value. This f-string feature is useful for inserting quick debugging checks in your code.
A string containing all the characters that are considered lowercase letters. On most systems this is the string 'abcdefghijklmnopqrstuvwxyz'. Do not change its definition — the effect on the routines upper() and swapcase() is undefined. The specific value is locale-dependent, and will be up...
As you saw earlier, it is possible for you to use backslash escapes in the string portion of an f-string. However, you can’t use backslashes to escape in the expression part of an f-string: 如前所述,可以在f字符串的字符串部分中使用反斜杠转义符。 但是,不能在F字符串的表达式部分中使用...
replacement repl. repl can be either a string or a callable; if a string, backslash escapes in it are processed. If it is a callable, it's passed the match object and must return a replacement string to be used. return _compile(pattern, flags).sub(repl, string, count) ...
In Python, a string is a sequence of characters. For example,"hello"is a string containing a sequence of characters'h','e','l','l', and'o'. We use single quotes or double quotes to represent a string in Python. For example, ...
In a usual python string, the backslash is used to escape characters that may have a special meaning (like single-quote, double-quote, and the backslash itself). >>> "wt\"f" 'wt"f' In a raw string literal (as indicated by the prefix r), the backslashes pass themselves as is ...
Another method which can be used for splitting strings ispartition. It will split the string at the first occurrence of the separator and return a 3-tuple containing the part before the separator, the separator itself, and the part after the separator. ...
if a string, backslash escapes in it are processed. If it is a callable, it’s passed the match object and must return a replacement string to be used. 实例: #把abc替换成def >>> re.sub("abc","def","abc123abc")'def123def' ...
