# 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")
