python - 在为用户输入分配变量时如何修复代码中的 "invalid syntax"错误？

Question

在第 3 行，名为 temp_unit 的变量不被视为变量，并且显示无效语法。

temp = int(input("what is the Temperature?:")
temp_unit = input("Celcius or Farenheit?:")
if temp_unit == "C" or temp_unit=="c":
    print("The given temperature in Fahrenheit is "+(9/5)*(temp+32))
else:
    print("The given temperature in Celcius is "+(5/9)*(temp-32))

Answer 1

您需要添加括号，因此应该是这样的:

temp=int(input("what is the Temperature?:"))
temp_unit= input("Celcius or Farenheit?:")
if temp_unit == "C" or temp_unit=="c":
    print("The given temperature in Fahrenheit is "+(9/5)*(temp+32))
else:
    print("The given temperature in Celcius is "+(5/9)*(temp-32))
