python 基础 列表 字符串转换
1. 字符串转列表
str1 = "hi hello world"
print(str1.split(" "))
输出:
['hi', 'hello', 'world']
2.字典变换为 list
dict.items()
3. 列表转字符串
l = ["hi","hello","world"]
print(" ".join(l))
输出:
hi hello world
str1 = "hi hello world"
print(str1.split(" "))
输出:
['hi', 'hello', 'world']
dict.items()
l = ["hi","hello","world"]
print(" ".join(l))
输出:
hi hello world
