尝试打印一个int，但它附带了：TypeError必须是str，而不是float

Question

I'm trying to get my program to print an int which follows a string. I'm not sure if that affects it or what but it comes up with the error whenever it tries to print.

I've tried using "," instead but I don't want to as it outputs The Price Is £ 7.0 but it doesn't look as good as £7.0

price = 10
age = int(input("How Old Are You? - "))
if age > 12 and age < 14:
  price = price * 0.7

print("The Price Is £"+price)

Answer 1

price is a float, so it cannot be concatenated to a string. Use string formatting instead:

print(f"The Price Is {price}£")

For example:

>>> price = 0.7
>>> print(f"The Price Is {price}£")
The Price Is 0.7£

Answer 2

发生这种情况是因为您必须将int连接起来：

print("The Price Is £"+str(price))

Answer 3

Try this:

print("The Price Is {}£".format(price))

Or

print("The Price Is £",price)
