Hello I am trying to display "5 + 5 = 10" with the syntax as follows print ("2 + 2 = " + ( 2 + 2) )
问题
我正在尝试使用以下语法显示 "5 + 5 = 10"：print ("2 + 2 = " + ( 2 + 2) )，但是我一直收到错误信息：
" TypeError: must be str, not int"
感谢帮助 
我尝试过：str ("2 + 2 = " + ( 2 + 2) )

没人建议使用 f-strings：
print(f'2 + 2 = {2 + 2}')
或者（自 Python 3.8 起）：
print(f'{2 + 2 = }')
英文:
Nobody suggested the f-strings:
print(f'2 + 2 = {2 + 2}')
Or even (since python3.8):
print(f'{2 + 2 = }')

在Python中，它是不同的类型，你不能在str和int类型之间使用+运算符。对于你的情况，你可以按照以下方式编写：
-
将int转换为str：
"2 + 2 = " + str(2 + 2)
-
使用str.format方法：
"2+2={:d}".format(2 + 2)
英文:
In python, it's different type,and you could not use + operator on type str and int.
for your case you can write below:
1.cover int to str:
"2 + 2 = " + str( 2 + 2)
2.use str.format method
"2+2={:d}".format(2+2)

你需要将`2+2`转换为字符串，然后再将其连接到`"2+2"`之后。```pythonprint("2 + 2 = "+str(2+2))
或者使用f-strings更好
print(f"2 + 2 = {2+2}")
如果你想避免重复求和，你可以使用devtools库（需要通过pip安装）
from devtools import debugdebug(f"{3+5=}")
>>> '3+5=8'
英文:
You have to convert 2+2 into a string before concatenating it to "2+2".
print("2 + 2 = "+str(2+2))
or even better, with f-strings
print(f"2 + 2 = {2+2}")
If you want to avoid repeating the sum, you can use the devtools library (to be installed via pip)
from devtools import debugdebug(f"{3+5=}")
>>> '3+5=8'

将一个字符串 "2 + 2 =" 添加到一个整数 (4) 中。首先将整数转换为字符串，然后将这两个字符串相加：
"2 + 2 = " + str(2 + 2)
英文:
You are trying to add a string "2 + 2 =" to an int (4). Turn the int into a string first and then add the two strings together:
"2 + 2 = " + str(2 + 2)

'+'操作符在Python中将两个相同类型的项目相加 - 两个字符串连接在一起变得更长，或者两个数字相加变成一个组合的单个数字。你正在将一个字符串'"2+2="'和一个数字(2+2)=4相加，这在逻辑上是没有意义的。要么将两者都变成字符串`print(""2 + 2 = "" + str(2 + 2))`要么依赖print将数字转换为字符串进行输出，去掉'+'号，并加上逗号以显示你正在打印两个不同的东西。`print(""2 + 2 = "", (2 + 2))`
英文:
The + operand in python adds 2 items of the same type together - two strings join to become longer, or two numbers add to become a combined single number. Yuo are adding a string "2+2=" to a number (2+2)=4, which doesn't make logical sense.
Either make both strings
print ("2 + 2 = " + str( 2 + 2) )
or rely on print to transform the numbers into strings for output, remove the + sign, and add a comma to show that you are printing two separate things.
print ("2 + 2 = ", ( 2 + 2) )
