在python中，如何在字符串后打印数字的总和？

Question

我想在python中的同一行中的字符串后打印numebr的总和

print("Your answer is correct, this is your score:" + score=score+1)

Answer 1

有两种方法

>>> score = 10 #you do your calculation first
>>> print("Your answer is correct, this is your score:", score)#print can take any number of arguments
Your answer is correct, this is your score: 10
>>> print("Your answer is correct, this is your score: " + str(score))#make it a string first and concatenate it
Your answer is correct, this is your score: 10
>>> print(f"Your answer is correct, this is your score: {score}")#use f-string
Your answer is correct, this is your score: 10
>>> 

还有2到3种制作字符串的方法，但是第一个和第三个例子是我推荐的，特别是f-string，它们非常棒

此外，在Python3.8中，它们引入了assignment expression:=，因此您也可以像最初尝试的那样进行操作，只需进行一些调整

>>> score=10 
>>> print("Your answer is correct, this is your score:", (score:=score+1))
Your answer is correct, this is your score: 11
>>> score
11
>>> 

Answer 2

打印前，将分数加1

在连接分数之前，还需要将分数转换为字符串。或者，您可以使用更简单的字符串格式

score += 1
print(f"Your answer is correct, this is your score: {score}"

Answer 3

如果使用f字符串，则可以在格式设置中添加操作：

print(f"Your answer is correct, this is your score: {score+1}")
