如何将字符串和变量插入打印语句中？

Question

我正在尝试编程一些将显示我在打印语句中写的变量的内容，但是每当我运行代码时，它都不会显示变量，它只是说“无”。

我的代码：

sidewalkclosed = True
raining = True
xPos = 400
yPos = 400
print("Your robot is located at",print(yPos),"on the y axis and",print(xPos),"on the x 
axis.")

Answer 1

尝试一下。

sidewalkclosed = True
raining = True
xPos = 400
yPos = 400
print("Your robot is located at",yPos,"on the y axis and",xPos,"on the x 
axis.")
#### or ####
print(f"Your robot is located at {yPos} on the y axis and {xPos} on the x 
axis.")
# More Ways
#### or ####
print("Your robot is located at {} on the y axis and {} on the x axis.".format(yPos,xPos))

#### or ####
print("Your robot is located at %d on the y axis and %d on the x axis." % (yPos,xPos))
# Here %d (Or %i) for integer and for string type you can use %s.
# And for float you can use (%f,%e,%g) and more.

错误

，您没有得到，而不是400和400，这是因为打印功能返回无。

执行您的代码。

print("Your robot is located at",print(yPos),"on the y axis and",print(xPos),"on the x 
axis.")

从代码中输出

400
400
Your robot is located at None on the y axis and None on the x axis.

当打印函数读取他获得的输入时，在此代码中
print（ypos）和print（xpos）他运行了这两个打印功能，并且
捕获返回值无。

Answer 2

我建议使用F字符串 -

print(f"Your robot is located at {yPos} on the y axis and {xPos} on the x axis")

Answer 3

由于某种原因，您已经将print（）insral print（）更改为

print("Your robot is located at",yPos,"on the y axis and",xPos,"on the x axis.")

Answer 4

sidewalkclosed = True
raining = True
xPos = 400
yPos = 400
print(f"Your robot is located at {yPos} on the y axis and {xPos} on the x axis.")
