tuple元组怎么替换字符应聘,电气类 自动化类 笔试题目C语言程序设计——课程设计——通讯录管理系统用友t3运行时错误字符串后的引号不完整C语言课程设计tuple元组怎么替换字符In?[135]:?a?=?range(5)
In?[136]:?a
Out[136]:?[0,?1,?2,?3,?4]以上a为创建的列表。
将列表a转化为tuple?b：
In?[137]:?b?=?tuple(a)
In?[138]:?b
Out[138]:?(0,?1,?2,?3,?4)将列表a转化为字符列表：
In?[139]:?map(str,a)
Out[139]:?['0',?'1',?'2',?'3',?'4']将列表a转化为字符串：
In?[149]:?''.join(map(str,a))
Out[149]:?'01234'
将tuple?b转化为list：
In?[150]:?list(b)
Out[150]:?[0,?1,?2,?3,?4]将tuple?b转化为字符列表：
In?[153]:?c=map(str,b)
In?[154]:?c
Out[154]:?['0',?'1',?'2',?'3',?'4']将tuple?b转化为字符串：
In?[155]:?''.join(map(str,b))
Out[155]:?'01234'
将字符列表c转化为数值列表：
In?[157]:?map(int,?c)
Out[157]:?[0,?1,?2,?3,?4]将字符列表c转化为tuple：
In?[163]:?tuple(c)
Out[163]:?('0',?'1',?'2',?'3',?'4')
将字符串分割为字符列表时，需要指定分隔符，默认为空格与制表符。例如：
In?[164]:?st?=?'t1=1;t2=2;t3=3'
In?[166]:?st.split(';')
Out[166]:?['t1=1',?'t2=2',?'t3=3']分隔符长度可以不止一个字符。
