1.字符拼接：

 1 name = input("name:")
 2 age = input("age:")
 3 job = input("job:")
 4 salary = input("salary:")
 5 
 6 info = '''
 7 name = {_name}
 8 age = {_age}
 9 job = {_job}
10 salary = {_salary}
11 '''.format(_name=name,_age=age,_job=job,_salary=salary)
12 
13 print(into)

 

2.if else：

1 age_of_liu = 56
2 guess_age = int(input("guess age:"))
3 
4 if age_of_liu == guess_age:
5     print("good!!!你猜对了。。666666")
6 elif age_of_liu > guess_age:
7     print("往大了想。。。")
8 else:
9     print("往小了想想。。。")

 

3.while：

 1 age_of_liu = 56
 2 count = 0
 3 
 4 while count < 3:
 5     guess_age = int(input("guess age:"))
 6     if age_of_liu == guess_age:
 7       print("good!!!你猜对了。。666666")
 8       break
 9     elif age_of_liu > guess_age:
10        print("往大了想。。。")
11     else:
12         print("往小了想想。。。")
13     count+=1
14 else:
15     print("猜错太多次，，，fuck off")
