格式化字符串：

name=input("input your name:")
age=int(input("input your age:"))
job=input("input your job:")
msg='''
information of user %s:
============================
Name: %s
Age: %d
Job: %s
-----------End--------------
'''%(name,name,age,job)
print(msg)

Tab补全：

#!/usr/bin/env python 
# python startup file 
import sys
import readline
import rlcompleter
import atexit
import os
# tab completion 
readline.parse_and_bind('tab: complete')
# history file 
histfile = os.path.join(os.environ['HOME'], '.pythonhistory')
try:
    readline.read_history_file(histfile)
except IOError:
    pass
atexit.register(readline.write_history_file, histfile)
del os, histfile, readline, rlcompleter

if...else语句 验证用户登录：

#!/usr/bin/python
#-*-coding:utf-8 -*-
age=25
counter=0
for i in range(10):
    if counter<3:
        guess_num=int(input("Input an num:"))
        if guess_num==age:
            print("you are right")
            break
        elif guess_num>age:
            print("it is > age")
        else:
            print("it is < age")
    else:
        #print("你已经输错了3次")
        #break
        continue_confirm=input("you are attempt three times,Are you continue")
        if continue_confirm=='y':
            counter=0
            continue   # 跳出当次循环进入下一个循环
        else:
            print("bye")
            break
    counter=counter+1
    if i>10:
        print("你已经超过10次")
