"Can't convert 'float' object to str implicitly"
提问by Inferno
>>> def main():
fahrenheit = eval(input("Enter the value for F: "))
celsius = fahrenheit - 32 * 5/9
print("The value from Fahrenheit to Celsius is " + celsius)
>>> main()
Enter the value for F: 32
Traceback (most recent call last):
File "<pyshell#73>", line 1, in <module>
main()
File "<pyshell#72>", line 4, in main
print("The value from Fahrenheit to Celsius is " + celsius)
TypeError: Can't convert 'float' object to str implicitly"

floatscan't be implicitly converted into strings. You need to do it explicitly.
floats不能隐式转换为字符串。你需要明确地做到这一点。
print("The value from Fahrenheit to Celsius is " + str(celsius))
But it's better to use format.
但最好使用format.
print("The value from Fahrenheit to Celsius is {0}".format(celsius))

As the error says, you cannot covert float object to string implicitly. You have to do :
正如错误所说，您不能将浮动对象隐式转换为字符串。你必须要做 ：
print("The value from Fahrenheit to Celsius is " + str(celsius))
