在基本的概念和数据结构了解完后,再了解一下基本语法来将这些零件合理的组合起来,这样就可以用 Python 干一下复杂的任务了.
条件语句
代码演示
1score = 70 2if score > 100 : 3 print 'the score is out of range.' 4elif score > 60 : 5 print 'your score is from 60 to 100.' 6elif score > 0 : 7 print 'your score is from 0 to 60.' 8else : 9 print 'the score is out of range.'
for循环语句
代码演示
1colors = ['red','blue','green'] 2 3for color in colors 4 print 'color is ' + color
1# print the numbers from 0 through 99 2for i in range(100): 3 print i
while循环语句
代码演示
1# list中元素a在哪个位置 2i = 0 3while i < len(list): 4 if list[i] == a : 5 print i 6 break 7 else : 8 i += 1
