一、函数
函数是一种模块化可重用代码片段的方法。
- 函数分为两块:一个是函数的定义;一个是函数的调用
- 函数的定义即def 后面的,其中这里的参数叫做形参
- 函数的调用时的参数叫做实参
Practise 1:
# Create a function
def add_two(x):
x += 2
return x
# Use the function
score = 0
score = add_two(x=score)
print (score)
输出结果:
2
Practise 2:
# Function with multiple inputs
def join_name(first_name, last_name):
joined_name = first_name + " " + last_name
return joined_name
# Use the function
first_name = "Goku"
last_name = "Mohandas"
joined_name = join_name(first_name=first_name, last_name=last_name)
print (joined_name)
输出结果:
Goku Mohandas
