You can use pandas.to_datetime :

df = pd.read_csv("https://github.com/prateek071995/Help/blob/main/project_data.csv?raw=true")

df["purhcase_date"] = pd.to_datetime(df["purhcase_date"]) # <- if need a specific format, add `.dt.strftime("%d/%m/%Y")`

Output :

print(df)

     customer_id purhcase_date  ...  calls  intercoms
0       20201701    04/09/2012  ...      3         11
