我想在Python中将整数转换为字符串.我是徒劳地捣蛋:
d = 15
d.str()
当我尝试将其转换为字符串时,它显示的错误就像int没有调用任何属性一样str.
如果我尝试执行以下操作:
things = 5
print("You have " + things + " things.")
我在Python 3.x中收到以下错误:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: must be str, not int
......以及Python 2.x中的类似错误:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: cannot concatenate 'str' and 'int' objects
我怎样才能解决这个问题？
>>> 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"
我读了其他的问题,但我试图做的事情是不同的我试图在python中制作一个计算器,并试图将变量输入事物变成一个整数,所以我可以添加它.这是我的代码还没有完成,我是一个初学者:
print("Hello! Whats your name?")
myName = input()
print("What do you want me to do? " + myName)
print("I can add, subtract, multiply and divide.")
option = input('I want you to ')
if option == 'add':
print('Enter a number.')
firstNumber = input()
firstNumber = int(firstNumber)
print('Enter another number.')
secondNumber = input()
secondNumber = int(secondNumber)
answer = firstNumber + secondNumber
print('The answer is ' + answer)
它能做什么:
Hello! Whats your name?
Jason
What do you want me to do? Jason
I …
