python 5 条件判断和循环

#!/usr/bin/env python # -*- coding: utf⑻ -*- age = 3 if age >= 18: print 'adult' elif age >= 6: print 'teenager' else: print 'kid' print '----------------------' names = ['jie', 'bob', 'trcy'] for name in names: print name print '------------------------' sum = 0 for x in [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]: sum = sum + x print sum print u'-----------range(整数生成)----------------' sum = 0 for x in range(101): sum = sum + x print sum print u'------while---------------' sum = 0 n = 3 while n>0: sum = sum + n n = n ⑵ sum = sum - 1 print sum print u'---------输入raw_input---------------' birth = int(raw_input('birth:')) #注意raw_input输入的数据都是字符 if birth<20: print u'00前' else: print u'00后'

注意代码保存的格式是utf⑻

:

IndentationError: unindent does not match any outer indentation level

遇到这个毛病是告知我们缩进不对

print u'------while---------------'
sum = 0
n = 3
while n>0:
sum = sum + n
n = n ⑵
sum = sum - 1  
 #容易出现缩进毛病,Tab和空格的不同,解决办法是sum = sum - 1移动到上1行,回车让Editplus帮我们换行
print sum
这里有趣的事sum = sum - 1位置的不同(前面是不是有Tab,决定了sum = sum - 1 语句是不是属于while{}中
