python - 打印字符串的单个字符 Python

Question

我的代码读取

import time
a = raw_input("Enter a string: ")
b = len(a)
#print 1st letter of string
time.sleep(2)
#print 2nd letter of string
#continue doing that until the last character in the string

我需要做什么才能让我的代码在 Python 2.7 中做到这一点？对正确方向的刺激将不胜感激。

谢谢你。

Answer 1

您可以遍历字符串本身：

import time
a = raw_input("Enter a string: ")
for char in a:      #iterate over string one character at a time
   print char
   time.sleep(2)    # sleep after printing each character

例子：

>>> for x in "foobar":
...     print x
...     
f
o
o
b
a
r

Answer 2

In [1]: t = 'input string'

In [2]: for c in t:
   ...:     print c
   ...:     
i
n
p
u
t

s
t
r
i
n
g
