在使用python3時，有【並行迭代】與【按索引迭代】，並行迭代相對來講好理解，如今介紹下【按索引迭代】。python

廢話很少，直接上實例
ide

# Demo：並行迭代 zip函數函數

names = ["anne","beth","george","damon","bob"]測試

ages = [12,45,32,102,101,103]spa

# names 與 ages 列表元素能夠不等同，按數量少的進行對應索引

for name,age in zip(names,ages):ip

print(name,"is",age,"years old!")string

按索引迭代案例it

按索引迭代方式一table

strings = ["Alice","Bob","Nick"]

# strings[1] = "leo" #測試給列表添加元素後，的效果

# print(strings)

index = 0

for string in strings:

if "ob" in string:

strings[index] = "Tom" # 將含有「ob」的元素，替換爲Tom

index += 1

print(strings)

按索引迭代方式二

strings = ["Alice","Bob","Nick"]

index = 0

for index,string in enumerate(strings):

if "ob" in string:

strings[index] = "Tom"

print(strings)
