Python TypeError must be str not int
提问by Eps12 Gaming
I am having trouble with the following piece of code:
我在使用以下代码时遇到问题：
if verb == "stoke":
if items["furnace"] >= 1:
print("going to stoke the furnace")
if items["coal"] >= 1:
print("successful!")
temperature += 250
print("the furnace is now " + (temperature) + "degrees!")
^this line is where the issue is occuring
else:
print("you can't")
else:
print("you have nothing to stoke")
The resulting error comes up as the following:
结果错误如下：
Traceback(most recent call last):
File "C:\Users\User\Documents\Python\smelting game 0.3.1 build
incomplete.py"
, line 227, in <module>
print("the furnace is now " + (temperature) + "degrees!")
TypeError: must be str, not int
I am unsure what the problem is as i have changed the name from temp to temperature and added the brackets around temperature but still the error occurs.
我不确定问题是什么，因为我已将名称从 temp 更改为温度并在温度周围添加了括号，但仍然发生错误。

print("the furnace is now " + str(temperature) + "degrees!")
print("the furnace is now " + str(temperature) + "degrees!")
cast it to str
投给 str

Python comes with numerous ways of formatting strings:
Python 提供了多种格式化字符串的方法：
New style .format(), which supports a rich formatting mini-language:
新样式.format()，支持丰富格式的迷你语言：
>>> temperature = 10
>>> print("the furnace is now {} degrees!".format(temperature))
the furnace is now 10 degrees!
Old style %format specifier:
旧式%格式说明符：
>>> print("the furnace is now %d degrees!" % temperature)
the furnace is now 10 degrees!
In Py 3.6 using the new f""format strings:
在 Py 3.6 中使用新的f""格式字符串：
>>> print(f"the furnace is now {temperature} degrees!")
the furnace is now 10 degrees!
Or using print()s default separator:
或者使用print()s 默认separator：
>>> print("the furnace is now", temperature, "degrees!")
the furnace is now 10 degrees!
And least effectively, construct a new string by casting it to a str()and concatenating:
最不有效的是，通过将其转换为 astr()并连接来构造一个新字符串：
>>> print("the furnace is now " + str(temperature) + " degrees!")
the furnace is now 10 degrees!
Or join()ing it:
或者join()它：
>>> print(' '.join(["the furnace is now", str(temperature), "degrees!"]))
the furnace is now 10 degrees!

you need to cast int to str before concatenating. for that use str(temperature). Or you can print the same output using ,if you don't want to convert like this.
您需要在连接之前将 int 转换为 str 。对于那个用途str(temperature)。或者，,如果您不想像这样进行转换，则可以使用打印相同的输出。
print("the furnace is now",temperature , "degrees!")
