python实例字符串

比起C/C++,Python处理字符串的方式实在太让人感动了.把字符串当列表来用吧.

#! /usr/bin/python

word="abcdefg"
a=word[2]
print ("a is: "+a)
b=word[1:3]
print ("b is: "+b) # index 1 and 2 elements of word.
c=word[:2]
print ("c is: "+c) # index 0 and 1 elements of word.
d=word[0:]
print ("d is: "+d) # All elements of word.
e=word[:2]+word[2:]
print ("e is: "+e) # All elements of word.
f=word[-1]
print ("f is: "+f) # The last elements of word.
g=word[-4:-2]
print ("g is: "+g) # index 3 and 4 elements of word.
h=word[-2:]
print ("h is: "+h) # The last two elements.
i=word[:-2]
print ("i is: "+i) # Everything except the last two characters
l=len(word)
print ("Length of word is: "+ str(l))

中文和英文的字符串长度是否一样?

#! /usr/bin/python
# -*- coding: utf8 -*-

s=input("输入你的中文名,按回车继续");
print ("你的名字是 : " +s)

l=len(s)
print ("你中文名字的长度是:"+str(l))

知识点:

类似Java,在python3里所有字符串都是unicode,所以长度一致.
