IF 判断
2、循环判断
 
 
FOR循环
 
for i in range(1,5):
        print i
for i in range(5):
        print i
2、循环判断
 
 
用变量控制循环次数：
  1. #!/usr/bin/python
list=['lk','tom','jack']
a=4
for name in range(1,a):
        print name
 
小练习：for和if结合用
  1. [root@likun python_scripts]# cat 4for.py 
#!/usr/bin/python
list=['lk','tom','jack']
for name in list:
        if name=='lk':
                print name,' is very good!'
        else:
                print name
print 'loop over!'

[root@likun python_scripts]# python 4for.py 
lk  is very good!
tom
jack
loop over!
 
WHILE循环
 
  1. [root@likun python_scripts]# cat 5while.py 
#!/usr/bin/python
whileTrue:
        input=raw_input('(alive|dead|other):')
        if input=='alive':
                print 'The process is ',input
        else:
                print 'The process is ',input
                break
