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
