打印字符串的单个字符

Question

我的代码是

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python2.7中做到这一点？ 如能按正确方向操作，将不胜感激。你知道吗

谢谢你。你知道吗

Answer 1

您可以迭代字符串本身：

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

示例：

>>> 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
