一、格式化输出

# 1、格式化输出 %：占位符 s：字符串 d：数字 %%：转义
name = input("your name:  ")
age = int(input("your age:  "))
height = int(input("your height:  "))
msg = "name: %s, age: %d, height: %d" %(name, age, height)
print(msg)

name = input("your name:  ")
age = int(input("your age:  "))
job = input("your job:  ")
hobbie = input("your hobbie:  ")
msg = ‘‘‘------------- index of %s -------------
name = %s
age = %d
job = %s
hobbie = %s
------------- end of %s -------------
‘‘‘ % (name, name, age, job, hobbie, name)
print(msg)

name = input("your name:  ")
age = int(input("your age:  "))
height = int(input("your height:  "))
msg = "name: %s, age: %d, height: %d,xx:  3%%" % (name, age, height)    # %用于转义
print(msg)

# 2、while-else 如果while没有被break打断则会执行else中的语句，否则不会
count = 0
while count <= 5:
    count += 1
    if count == 3:
        break
else:
    print("over")
