本文介绍了使用Python进行名字格式化输出的四种方法，包括不同参数组合的函数定义，以及一个循环读取用户输入并返回格式化名字的示例。

编写一个python脚本，格式化输出名字。

这个案列一共列举了四种写法：

## 1
# def get_formatted_name(first_name,last_name):
# 	full_name = first_name + ' ' + last_name
# 	return full_name.title()
# 
# musician = get_formatted_name('jimi','hendrix')
# print(musician)
# print()

## 2
# print()
# def get_formatted_name(first_name,middle_name,last_name):
# 	full_name = first_name + ' ' + middle_name + ' ' + last_name
# 	return full_name.title()
# 
# musician = get_formatted_name('jhon','lee','hooker')
# print(musician)
# print()

## 3
# print()
# def get_formatted_name(first_name,last_name,middle_name=''):
# 	if middle_name:
# 		full_name = first_name + ' ' + middle_name + ' ' + last_name
# 	else:
# 		full_name = first_name + ' ' + last_name
# 	return full_name.title()
# 
# musician = get_formatted_name('jhon','lee','hooker')
# print(musician)
# print()
# 
# musician = get_formatted_name('jhon','hooker')
# print(musician)
# print()

## 4
def get_formatted_name(first_name,last_name):
	full_name = first_name + ' ' + last_name
	return full_name.title()

while True:
	print("\nPlease tell me your name:")
	f_name = input("First name: ")
	if f_name == '':
		break
	l_name = input("Last name: ")
	if l_name == '':
		break
	formatted_name = get_formatted_name(f_name,l_name)
	print("\nHello, " + formatted_name + "!")
