如何在 Python 中获取这个华氏到摄氏代码以返回值而不是公式？

Question

def c_to_f ():
  c_temp= float(input("Enter temperature in Celsius to convert to Fahrenheit"))
  f_temp= float(1.8 *c_temp) + 32



c_to_f()
print("The value in Fahrenheit is: " + f_temp)

The output***:

Enter temperature in Celsius to convert to Fahrenheit56
The value in Fahrenheit is: float(1.8 * c_temp) + 32

enter image description here

Answer 1

You have to return the created function object first:

def c_to_f (): 
    c_temp= float(input("Enter temperature in Celsius to convert to Fahrenheit")) 
    f_temp= float(1.8 *c_temp) + 32
    return f_temp
a = c_to_f() 

# Return the object as string
print("The value in Fahrenheit is: " + str(a))

# Using printf
print(f"The value in Fahrenheit is: {a}")

Enter temperature in Celsius to convert to Fahrenheit34
The value in Fahrenheit is: 93.2
The value in Fahrenheit is: 93.2
