How to make python process inputs from command line?

I have a python script that will ultimately be converted into an .exe file. The way it is supposed to work is that a user will drag an excel file and drop it on to the python file, which will run, and create another output excel file.

However, it needs 2 inputs from the user: groups and size.

When I drop the excel file, the command prompt opens up automatically, and prompts me for the inputs. However, after submitting the values, the command prompt closes automatically without executing the rest of the script.

The problem goes away if I hard-code the values for groups and size without prompting the user.

Here is the code:

import pandas as pd 
import sys

x = sys.argv[1]
file = pd.read_excel(x)
file = file.sample(frac=1).reset_index(drop=True)
file['Order'] = file.groupby('GENDER').cumcount()
file = file.sort_values(['Order', 'GENDER'], ascending=[True,False]).reset_index(drop=True)

groups = input ("Group number?") 
size = input ("Group size?") 
out = {}
count = 1
students = len(file)
std_sorted = 0

for i in range (0, len(file)-size, size): 
    if count != groups: 
        out["group"+str(count)] = file[i:(i+size)]
    else: 
        out["group"+str(count)] = file[i:]       
    count += 1 
    std_sorted += size 


if std_sorted != students: 
    out["group"+str(count)] = file[std_sorted:]

index = 0
writer = pd.ExcelWriter('output.xlsx')
for i in out:
    out[i].pop("Order")
    x = pd.DataFrame(out[i])
    x.to_excel(writer, index = False, sheet_name="Sheet"+str(index))
    workbook = writer.book # Access the workbook
    worksheet= writer.sheets["Sheet"+str(index)] # Access the Worksheet

    header_list = x.columns.values.tolist() # Generate list of headers
    for i in range(0, len(header_list)):
        worksheet.set_column(i, i, len(header_list[i])+2) # Set column widths based on len(header)

    index += 1

writer.save()
