string = "Hello:World:Python" result = string.split(":") print(result) 输出结果为: 代码语言:txt 复制 ['Hello', 'World', 'Python'] 在上述代码中,我们定义了一个字符串变量string,其中包含了冒号字符。然后,我们使用split()方法对字符串进行拆分操作,传入冒号字符作为分隔符。split()方法会返回一个...

string.split(separator,max)#separator:可选,规定分割字符时要使用的分隔符,默认值为空白字符。max:可选,规定要执行的拆分数,默认值为-1,即“所有出现次数”。 #!/usr/bin/python #将字符串拆分为最多2个项目的列表 txt="apple#banana#cherry#orange" ...
