In addition, we canaccess just a specific characteror aslice of charactersof a string. We might want to do this, for example, if we have a text that’s too long to display and we want to show just a portion of it. Or if we want to make an acronym by taking the first letter of...
Out[36]: 'welcom to python,age is 20' 填充与格式化: In [53]: "{0: >20}".format("string") #从0位开始已空格填充20宽度左对齐 Out[53]: ' string' In [54]: "{0:&>20}".format("string") Out[54]: '&&&&&&string' In [55]: "{0:#>20}".format("string") #使用#号会有个...
Alternatively, the first character of the format string can be used to indicate the byte order, size and alignment of the packed data。 非此即彼:字符串的第一个字符要么被用于表示字符串的字节的排序,或者是字符串的size,还有就是数据是否对准。
defis_numeric(character):returncharacter.isnumeric()character='7'is_numeric=is_numeric(character)print(is_numeric) 运行以上代码,输出结果如下: 代码语言:txt AI代码解释 True 在这个示例中,我们定义了一个函数is_numeric,它接受一个字符作为参数。在函数体内,我们调用了字符对象的isnumeric()方法来判断字符是...
