#1 Created at ... [Delete] [Delete and Lock User]

在b站看的视频教程上，博主一直在用

name = 'xiaoming'
print(f'hello {name}!')

请问这也是一种格式吗，感觉这个更简单简洁

#2 Created at ... [Delete] [Delete and Lock User]

python3.8新增的特性，用来格式化字符串的，和%s、format类似，，不是编码

#3 Created at ... [Delete] [Delete and Lock User]

就用f的格式了，确实方便简单。

name = "李四"

money = 123.456

day = 5

print("你好，{name}")

print(f"你好，{name}，中奖￥{money:.2f}元") # 还可以这样写！

print(f"你好，{name}，中奖￥{54628.61458:.3f}元")

print(f"今天是：2020年{8:02d}月{day:3d}日")

#4 Created at ... [Delete] [Delete and Lock User]

这种感觉会明晰很多，花括号倒是稍微麻烦一点。
