Hi experts, I'll have to create a python file to store all myfunction in one file and main program in another, to make my codemuch neater. My main function will only include the menuoptions(Where I could select options) , functions andlist.
Example:
while True:
print(menu)
if choice == "1":
cross_vel()
elif choice == "2":
mean_vehicle()
elif choice == "3":
de_vehicle()
elif choice == "4":
cross_plot()
elif choice == "0":
break
else:
print("Wrong Choice")
full code:
