3. 将字符串s = "alex"转换成列表与元组 s = "alex" 将列表与元组进行相互转换

将字符串s = "alex"转换成列表:

s = "alex"
lst = list(s)
print(lst)  # ['a', 'l', 'e', 'x']

将字符串s = "alex"转换成元组:

s = "alex"
tup = tuple(s)
print(tup)  # ('a', 'l', 'e', 'x')

将列表转换成元组:

lst = ['a', 'l', 'e', 'x']
tup = tuple(lst)
print(tup)  # ('a', 'l', 'e', 'x')

将元组转换成列表:

tup = ('a', 'l', 'e', 'x')
lst = list(tup)
print(lst)  # ['a', 'l', 'e', 'x']
