Let’s look at a couple of common sequence operations on strings. 让我先定义一个字符串。 Let me first define a string. 让我们来看看“Python” Let’s just go with "Python." 同样,如果我想知道我的字符串有多长,我可以使用len函数。 Again, if I wanted to find out how long is my string,...
| Return S left-justified in a Unicode string of length width. Padding is | done using the specified fill character (default is a space). | | lower(...) | S.lower() -> str | | Return a copy of the string S converted to lowercase. | | lstrip(...) | S.lstrip([chars]) ->...
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. Returns a copy of format_string where each...

must be a string, whose characters will be mapped to None in the result. Docstring: S.translate(table) -> str Return a copy of the string S in which each character has been mapped through the given translation table. The table must implement ...
However, Python does not have a character data type, a single character is simply a string with a length of 1. Square brackets can be used to access elements of the string. Example Get the character at position 1 (remember that the first character has the position 0): ...
一、 SyntaxError 语法错误 （1）引号没有成对出现 报错信息：1SyntaxError:EOL while scanning string literal 错误示例：1string = 'hello world 解决方法：字符串切记要放在引号中，单引号双引号无所谓。当一个字符串中包含单引号或双引号时，很容易出现引号不配对的情况。（2）圆括号没有成对出现 报错信息：1...
word[-1]# Last character. 输出为: Output 'n' 同样地,其他负索引会从相应的位置返回字符: Python word[-2]# Second-to-last character. 输出为: Output 'o' 切片 Python 既支持索引,也支持切片,前者从字符串中提取单个字符,后者提取子字符串(或切片)。 若要进行切片,需采用“开始:结束”格式指示范围。
