Finding Duplicate in CSV file

[bond009]

I have CSV with entries like below. I want to generate the CSV file which merge the location into rows if the string before the ',' matches like shown in highlighted.

driver/travel1/,location1
driver/travel1/,location2
driver/travel1/,location3
driver/travel1/,location4
driver/travel1/,location5
driver/travel2/,location6
driver/travel2/,location7
driver/travel2/,location8
driver/travel2/,location9
driver/travel2/,location10


driver/travel1/,[location1:location2:location3:location4:location5]
driver/trave2/,[location6:location7:location8:location9:location10]

what have you tried?

I was trying with pandas, but looks like pandas is not supported in version3.8
Merge = df.read_csv('./Sort_output.txt')
df = df.groupby('Node').agg({'Child'})
print(df)
