在函数中包装代码

Question

写一个函数你好， 姓名你现在是今年的年龄 。

到目前为止我有这个：

from datetime import date
p = current_year = date.today().year

name = raw_input("enter your name")
y = raw_input("enter ur month of birth")
z = raw_input("enter your year of birth")

current_age =(int(p)-int(z))

print current_age
print("Hi,", name, " you are" , current_age, " years old this year!"
  "Here's a bouquet of flowers for you!")

这段代码有效，但我试图把它变成一个函数。 有人可以帮忙吗？

from datetime import date
p = current_year = date.today().year

def bday_wish(name,y,z):
    current_age =(int(p)-int(z))

print current_age
print("Hi,", name, " you are" , current_age, " this year!")

Answer 1

如果您想将个人信息作为参数，您可以使用：

from datetime import date

def display_birthday_wishes(name, month, year):
    p = current_year = date.today().year
    current_age = (int(p)-int(year))

    return "Hi, " + name + ". You are " + str(current_age) +\
    " years old this year! Here's a bouquet of flowers for you!"

print display_birthday_wishes("David", 4, 1998)

但是，如果您仍想使用raw_input获取信息，可以使用以下命令：

from datetime import date

def display_birthday_wishes():
    name = raw_input("enter your name")

    current_year = current_year = date.today().year
    year_born = raw_input("enter your year of birth")

    current_age = (int(current_year)-int(year_born))

    month_born = raw_input("enter your month of birth")


    return "Hi, " + name + ". You are " + str(current_age) +\
    " years old this year! Here's a bouquet of flowers for you!"

print display_birthday_wishes()

Answer 2

定义一个名为display_birthday_wishes的函数。 在里面放置你想要运行的代码，在需要时调用函数。

from datetime import date

def display_birthday_wishes(): #define the function, no arguments passed in
    p = current_year = date.today().year

    name = raw_input("Enter your name: ")
    y = raw_input("Enter the month you were born in: ")
    z = raw_input("Enter your year of birth ")

    current_age =(int(p)-int(z))

    print current_age
    print"Hi,", name, "you are" , current_age, "years old this year! Here's a bouquet of flowers for you!"

display_birthday_wishes() #call the function

from datetime import date


name = raw_input("enter your name")
y = raw_input("enter ur month of birth")
z = raw_input("enter your year of birth")

def display_birthday_wishes(name, month, year):
    p = current_year = date.today().year
    current_age =(int(p)-int(year))

    print current_age
    print("Hi,", name, " you are" , current_age, " years old this year!"
      "Here's a bouquet of flowers for you!")

display_birthday_wishes(name, y, z)
