In the above code, we have assigned the string “Charlie” to the variable called name and assigned the int value of 26 to the variable age. In the next step, we convert the age variable to string using the .format() function and print the string as shown in the output. ...
string 对象的 split() 方法只适应于非常简单的字符串分割情形,它并不允许有多个分隔符或者是分隔符周围不确定的空格。当你需要更加灵活的切割字符串的时候,最好使用re.split()方法: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>>line='asdf fjdk; afed, fjek,asdf, foo'>>>importre>>>re.spli...
