1.python 輸入和格式化輸出。

#!/usr/bin/evn python
# -*- coding:utf-8 -*-
# Author: Aron1)input輸入name = input("name:")
age = input("age:")
job = input("job:")
salary = input("salary:")
輸入的格式位str
格式轉換：
age = int(input("age:"))
輸入為int

2)格式化輸出的三種方式

①
info = ‘‘‘
------ info of {_name} ------
Name:{_name}
Age:{_age}
job:{_job}
salary:{_salary}

2.while循環以及for循環

1)while循環
_username = ‘Aron‘
_password = ‘abc123‘
count = 0
while True :
　　password = input("password:")
　　if _username == username and _password == password:
　　　　print("Welcome user {name} login...".format(name=username))

簡寫:

age_of_oldboy = 56
count = 0
while count < 3:
　　guess_age = int(input("guess age:"))
　　if guess_age == age_of_oldboy :
　　　　print("yes,you got it")
　　　　break
　　elif guess_age > age_of_oldboy :
　　　　print("think smaller...")
　　else:
　　　　print("think birgger!")
　　count += 1
　　if count == 3:
　　　　countine_confirm = input("do you want to keep guessing?")
　　　　if countine_confirm != ‘n‘:
　　　　count =0
else:
　　print("you have tried too many times..fuck off")

2)for 循環

age_of_oldboy = 56

for n in range(0,10,2):
　　print("loop",n)

for i in range(3):
　　guess_age = int(input("guess age:"))
　　if guess_age == age_of_oldboy :
　　　　print("yes,you got it")
　　　　break
　　elif guess_age > age_of_oldboy :
　　　　print("think smaller...")
　　else:
　　　　print("think birgger!")
else:
　　print("you have tried too many times..fuck off")
