Python中print函数的格式化输出可以通过占位符的方式实现。常用的占位符有:
- %s:字符串
- %d:整数
- %f:浮点数
示例如下:
name = "Alice"
age = 20
height = 1.65
print("Hello, my name is %s, I am %d years old and %.2f meters tall." % (name, age, height))
另外,Python3.6及以上版本还支持使用f字符串进行格式化输出,示例如下:
name = "Alice"
age = 20
height = 1.65
print(f"Hello, my name is {name}, I am {age} years old and {height:.2f} meters tall.")
