第一次在这里发帖。我已经到处搜索以找出一种方法来做到这一点，但我要么不明白如何将现有答案应用于我的代码。
我想要做的是：我想接受用户输入（一年），确保它在几年之间，然后如果是的话，将它与现有字符串连接起来作为变量。
这段代码的结果是我通过并提供了所有必要的输入，然后它失败了 "fullInstr = str("cp -r /mnt/data/archive"+ fquery+ "/" + yquery+mquery+dquery+" /"+hquery+"*" + " " + outl2) TypeError: cannot concatenate 'str' and 'int' objects"
import os
import sys
os.system("clear")
overW = str("0")
outf = str("/autocopy.sh") # Output file full path and file name
if os.path.isfile("/autocopy.sh"): #
overW = raw_input("This will overwrite the previous version. Do you want to continue? (y/n) ")
os.system("clear")
else:
os.system("clear")
if overW != "y":
os.system("clear")
sys.exit("No changes made.\n\n")
else:
os.system("clear")
#! Could also prompt for output file name, depending on how army-proof this needs to be.

被注释掉的东西要么不起作用，要么尚未实施。我知道代码质量可能不是最好的，但这是我第一次编写代码来做我需要的事情。我已经尝试了很多东西，比如 yquery = str(yquery) 或者只是将 fullInstr 字符串更改为包含 str(yquery) ，但我无法让它工作。我变得沮丧。
