# lists ka Max and Min kaise nikale.
print(max(numbers)) # lists ke maximum value wale ke no. ko print karega.

# lists ka Alat palat ka kaam kaise kare me.
numbers.sort() # sort() fn. ka use lists ke no. ko accending order me daalne ke liye.

#lists me no. ko delete kaise kare.
numbers.pop(1)    #matlab index 1 wala No. delete hoga lists me se.
print(numbers)


#Tuples ka use kaise hota hai!!!
numbers[1] = 227 #tuples basically replacement ka kaam krta hai bs number[index No.] = any No. and yupp you got your new lists.
