如何在运行 GPT 命令时将变量作为输入

我想用 Python 中的 for 循环处理多张图片。

当我尝试对一个文件执行此操作时，它可以工作，例如： 

!gpt "Method/gpt_scripts/s1_cal_deb.xml" -t "result_step1/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip/s1_cal_deb/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip_Cal_deb_script.dim" "./Rader Images/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip"

但是我想对许多文件执行此操作，所以我在 Python 3 中测试了这一点。 

deb = (f'"{"Method/gpt_scripts/s1_cal_deb.xml"}"') 
deb = deb + " -t "

url = (f'"{"result_step1/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip"}')
url5 = (f'{"S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip"}')       
url2 = (f'{"/s1_cal_deb/"}')
url3 = (f'{url5}')
url4 = (f'{"_Cal_deb_script.dim"}"')
source = (f'"{"./Rader Images/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip"}"')

output = url + url2 + url3 + url4

final = deb + output + " " + source

final

输出： 

'"Method/gpt_scripts/s1_cal_deb.xml" -t "result_step1/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip/s1_cal_deb/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip_Cal_deb_script.dim" "./Rader Images/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip"'

最终字符串与第一个字符串完全相同。但我收到以下错误：

Error: Operator SPI not found for operator [final]

我在这里遗漏了一些非常明显的东西？我对 Python 中的 F 字符串还不熟悉，因此非常感谢您的帮助。

一些示例： 

deb = (f'"{"Method/gpt_scripts/s1_cal_deb.xml"}"') # This is the script to run
    deb = deb + " -t " 

url = (f'"{"result_step1/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip"}') # output folder
url5 = (f'{"S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip"}')  # input file      
url2 = (f'{"/s1_cal_deb/"}') # output folder
url3 = (f'{url5}') # filename
url4 = (f'{"_Cal_deb_script.dim"}"') # output file extention
source = (f'"{"./Rader Images/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip"}"') # input file 

output = url + url2 + url3 + url4

final = deb + output + " " + source

final

这将创建以下字符串：

输出： 

'"Method/gpt_scripts/s1_cal_deb.xml" -t "result_step1/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip/s1_cal_deb/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip_Cal_deb_script.dim" "./Rader Images/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip"'

但我想要以下字符串： 

 "Method/gpt_scripts/s1_cal_deb.xml" -t "result_step1/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip/s1_cal_deb/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip_Cal_deb_script.dim" "./Rader Images/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip"

我想要转换：

'"Method/gpt... to "Method/gpt... on both ends of the string

然后我可以按如下方式运行 !gpt 命令： 

!gpt final

我希望这更清楚。

非常感谢，

我已设法在 Python 中找到解决方案。 

#example command

command = 'cmd /k "gpt Method/gpt_scripts/s1_cal_deb.xml -t ../s1_pc/s1/deb/unit/S1A_IW_SLC__1SDV_20190224T003144_20190224T003211_026064_02E80B_0ECE_cal_deb.dim ../s1_pc/s1/s1_slc/unit1/S1A_IW_SLC__1SDV_20190224T003144_20190224T003211_026064_02E80B_0ECE.zip"'

os.system(command) # Start GPT command in the Jupyter Notebook cmd

这不是一个完整的答案，因为正如您将在下面看到的，问题可能出在 gpt 上（我对此不太熟悉）。但在试图弄清楚的过程中，我发现了一些可能对您有帮助的东西。 首先，您的代码不必要地复杂，并且 f 字符串（在这种情况下）不执行任何操作，只会使代码混乱。我会像这样重写它： 

deb = '"Method/gpt_scripts/s1_cal_deb.xml"' + " -t " 
url = "result_step1/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip"
url2 = "/s1_cal_deb/"
url3 = "S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip"
url4 = "_Cal_deb_script.dim" 

source = "./Rader Images/S1A_IW_SLC__1SDV_20190928T003154_20190928T003221_029214_035175_65FA.zip"
output = '"'+url+url2+url3+url4+'"'
final = deb + output + " " + '"'+source+'"'

这将使您得到与问题中相同的 final 。 至于字符串的问题：这是 python 的工作方式： 

hi = 'hi there!'
print(hi) #using the print method
hi #without using the print method

输出： 

hi there!   
'hi there!'

您注意到了差异吗？单引号实际上不是字符串的一部分，只是当您不发出打印命令时屏幕输出的一部分。这就是我说这不是一个完整答案的原因：我不知道如何强制 gpt 接受字符串本身作为参数。您可能希望将该特定问题（使用简化的“hi”示例）作为单独的问题发布。可能（很可能）比我聪明的人可以解决这个问题。

抱歉最后一部分；希望这对您有用....
