python中存在问题：显示错误只能将str（而不是“bool”）连接到str

Question

我对python还很陌生，如果您愿意说的话，我为“noob”代码感到抱歉。但请帮助我： 我尝试将两个数字相加，并显示哪一个作为布尔值更大

num_1 = input("Enter first number: ")    
num_2 = input("Enter second number: ")

num_1 = int(num_1)
num_2 = int(num_2)

Sum = num_1 + num_2

print(Sum)

Greater = num_1 > num_2
Smaller = num_1 < num_2

print("is number 1 greater than number 2?  " + Greater)
print("is number 2 greater than number 1?  " + Smaller)

Answer 1

执行字符串格式，该格式应打印true或false

print(f"is number 1 greater than number 2? {Greater} " )

print(f"is number 2 greater than number 1? {Smaller}" )

输出

Enter first number: 12
Enter second number: 33
45
is number 1 greater than number 2? False 
is number 2 greater than number 1? True

Answer 2

比较运算符的结果是布尔值（或者True或者False）。正如错误消息所说，不能将字符串与布尔值连接起来，因为Python是一种强类型语言。您有几个选择：

1. 将它们作为单独的参数传递给print函数：

   print("is number 1 greater than number 2?", Greater)
   print("is number 2 greater than number 1?", Smaller)
   

2. 使用f字串：

   print(f"is number 1 greater than number 2? {Greater}")
   print(f"is number 2 greater than number 1? {Smaller}")
   

3. 使用.format()：

   print("is number 1 greater than number 2? {}".format(Greater))
   print("is number 2 greater than number 1? {}".format(Smaller))
   

Answer 3

在使用str强制转换字符串后，可以将其与布尔值连接起来

num1 = int(input("Enter a number: "))
num2 = int(input("Enter a number: "))

sum = num1 + num2
print(sum)

greater = num1 > num2
smaller = num1 < num2

print("Is number 1 greater than number 2? " + str(greater))

print("Is number 2 greater than number 1? " + str(smaller))
