Python字符串类型

2用户输入一个字符串，将字符串按照每4个字符一行进行输出例如:输入abcdefg，输出 abcd efg

s = 'abcdefgdasdasdasdas'
step = 4
print([s[i:i+step] for i in range(0,len(s),step)])

s = input()
for i in range(0,len(s)):
    print(s[i],end="")
    if i % 4 == 3:
        print()

str_temp = input("请输入字符串：")
temp = ''
for index, s in enumerate(str_temp):
    temp += s
    if (index+1) % 4 == 0:
        temp += ' '

print(temp)
