转换 - string转list - list(string)

字符串直接变成列表[]

str_ = "1234"
list1 = list(str_)
print(list1)
print(type(list1))
# ['1', '2', '3', '4']
# <class 'list'>

str按照某符号拆分

s = "a s d"
str_list = s.split(sep=' ')   # 按空格拆
print(str_list)
print(type(str_list))
#  ['a', 's', 'd']
# <class 'list'>
s = "a<s<d"
str_list = s.split(sep='<')   # 按<拆
print(str_list)
print(type(str_list))
#  ['a', 's', 'd']
# <class 'list'>
