ascii(object) The repr() function returns a string containing a printable representation of an object and escapes the non-ASCII characters in the string returned by repr() using \x, \u or \U escapes. This generates a string similar to that returned by repr() in Python 2. Version: (Pyth...

最好的python课程 采用转义字符"\n"也可以换行 input() #收集信息 name=input('请输入你的forchangeID:') 使用变量赋值来获取输入的信息 注意:需要注意的是:input默认输出为字符串,在后面与int做条件判断的时候,需要先转换数据类型为int(input());同时数字做数据拼接时,需要使用str(number) ...
