字符串前面加上字母 f (代表 format), 比如 f"Hello, {somevar}" 。 双引号前面的 f 是为了告诉 python3: “这个字符串需要被格式化,把这些变量放在那儿。”
my_name = 'Zed A. Shaw' my_age = 35 # not a lie my_height = 74 # inches my_weight = 180 # lbs my_eyes = 'Blue' my_teeth = 'White' my_hair = 'Brown' print(f"Let's talk about {my_name}.") print(f"He's {my_height} inches tall.") print(f"He's {my_weight} pounds heavy.") print("Actually that's not too heavy.") print(f"He's got {my_eyes} eyes and {my_hair} hair.") print(f"His teeth are usually {my_teeth} depending on the coffee.") Let's talk about Zed A. Shaw. He's 74 inches tall. He's 180 pounds heavy. Actually that's not too heavy. He's got Blue eyes and Brown hair. His teeth are usually White depending on the coffee.用.format()括号里的内容,填补前面变量中{}的部分。
a 或者 snow 这种比较短的字符串应该用单引号
