python如何遍历元组
第一种,使用for in遍历。
girl_tuple = ("貂蝉", "狐狸精","范金链","翠花","小班") for everyOne in girl_tuple: print(everyOne)
输出结果:
貂蝉 狐狸精 范金链 翠花 小班
第二种,使用内置函数enumerate遍历。
girl_tuple = ("貂蝉", "狐狸精","范金链","翠花","小班") for index, everyOne in enumerate(girl_tuple): print str(index) + everyOne
输出结果:
貂蝉 狐狸精 范金链 翠花 小班
第三种,使用range()或者xrange()内置函数,会把传入的数字,分解成一个List,比如range(),那就是[0,1,2,3,4]。
girl_tuple = ("貂蝉", "狐狸精","范金链","翠花","小班") for index in range(len(girl_tuple)): print girl_tuple[index]
girl_tuple = ("貂蝉", "狐狸精","范金链","翠花","小班") for index in xrange(len(girl_tuple)): print girl_tuple[index]
输出结果:
貂蝉 狐狸精 范金链 翠花 小班
第四种,使用iter(),同样是内置函数,返回迭代器。
girl_tuple = ("貂蝉", "狐狸精","范金链","翠花","小班") for everyOne in iter(girl_tuple): print everyOne
输出结果:
貂蝉 狐狸精 范金链 翠花 小班
