Python之Tuple遍歷方式

Tuple的同樣需要遍歷嘛,只是一旦建立後,元素不可變,遍歷同List一樣

分開寫的原因是,就像那位大牛說的,層級都不要太深,本來就low,一下子放在一起,知識不好鞏固

 

0、直接上乾貨,第一種:for in

girl_tuple = ("貂蟬", "狐狸精","範金鏈","翠花","小班")

for everyOne in girl_tuple:
    print(everyOne)

輸出結果:

貂蟬
狐狸精
範金鏈
翠花
小班

1、第二種,使用內建函式enumerate,但我怎麼也找到一個同名的class

girl_tuple = ("貂蟬", "狐狸精","範金鏈","翠花","小班")

for index, everyOne in enumerate(girl_tuple):
    print str(index) + everyOne

輸出結果:

0貂蟬
1狐狸精
2範金鏈
3翠花
4小班

 

2、第三種,使用range()或者xrange(),這倆內建函式,會把傳入的數字,分解成一個List,比如range(5),那就是[0,1,2,3,4]

girl_tuple = ("貂蟬", "狐狸精","範金鏈","翠花","小班")

for index in range(len(girl_tuple)):
    print girl_tuple[index]
girl_tuple = ("貂蟬", "狐狸精","範金鏈","翠花","小班")

for index in xrange(len(girl_tuple)):
    print girl_tuple[index]

輸出結果:

貂蟬
狐狸精
範金鏈
翠花
小班

3、第四種,使用iter(),同樣是內建函式,返回迭代器,牛x

girl_tuple = ("貂蟬", "狐狸精","範金鏈","翠花","小班")

for everyOne in iter(girl_tuple):
    print everyOne

輸出結果:

貂蟬
狐狸精
範金鏈
翠花
小班
