如何在python中打印字符串后的数字和?

Question

我想在python中打印同一行字符串后面的数字和。

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

Answer 1

在打印前给加1。

您还需要将乐谱转换为字符串，然后才能将其连接起来。或者您可以使用字符串格式，这更简单。

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

Answer 2

如果使用f字符串，则可以在格式中添加操作:

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

Answer 3

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
>>> 

也有2或3种其他的方法来创建字符串，但我推荐的是第一个和第三个例子，特别是f-string，它们非常棒。

此外，在python 3.8中，他们引入了赋值表达式:=，所以你也可以像你最初尝试的那样做，只需要做一些调整…

>>> 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 4

您可以使用f-string，但您也应该在打印之前设置score的值，以便更清楚发生了什么:

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

您可以按照自己的方式操作，但是您必须先将score转换为字符串，然后才能将其(通过+)连接到另一个字符串:

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

另一种方法是将score作为参数添加到print;在这种情况下，您不必将其转换为字符串:

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