学习笔记：python (2)

python学习

1.列表

形式如下:

names = ['liuyufan','yebenhao','luyuhang']

调用列表中的内容：

names = ['liuyufan','yebenhao','luyuhang']

print = name[0]

#输出

liuyufan

2.合并两个字符串

使用方法：

first_name = "zhang"
last_name = "san"
full_name = f"{first_name}{last_name}"
print(full_name)


#输出格式如下
zhangsan

其中f"{a}{b}"即可实现上述操作

f为format的简写

3.修改字符串大小写

使用name.title()，name.upper()，name.lower()。names = ['liuyufan','yebenhao','luyuhang']print(f'{names[0].title()}是我儿')print(f'{names[2].title()}是我儿')print(f'{names[1].title()}是我儿')

name = "apple"
print(name.title())
print(name.upper())
print(name.lower())
#输出为
Apple
APPLE
apple

4.结合上述三点写出问候一下好朋友

names = ['liuyufan','yebenhao','luyuhang']
print(f'{names[0].title()}是我儿')
print(f'{names[2].title()}是我儿')
print(f'{names[1].title()}是我儿')
#输出为
Liuyufan是我儿
Luyuhang是我儿
Yebenhao是我儿
