python入门之列表推导式嵌套

# 传统写法:
list01 = ["a", "b", "c"]
list02 = ["A", "B", "C"]
list03 = []
for r in list01:
    for c in list02:
        list03.append(r + c)
print(list03)

 

# 列表推导式嵌套
list04 = [r + c for r in list01 for c in list02]
print(list04)

 

# 练习1：
#     ["香蕉","苹果","哈密瓜",]
#     ["可乐","牛奶",]

# 传统写法:
list01 = ["香蕉", "苹果", "哈密瓜", ]
list02 = ["可乐", "牛奶", ]
list03 = []
for r in list01:
    for c in list02:
        list03.append(r + c)
print(list03)

 

# 列表推导式嵌套
list04 = [r + c for r in list01 for c in list02]
print(list04)
