# declaring a function that takes a value n as a parameter
def sequence (n):
   # checking if n is not equal to 1, if yes moving into the loop
   while n != 1: # n ! == 1 will give error, this is not the correct syntax to compare values in python
      # printing the value
      print(n)
      # if n is an even number then diving n by 2 ( integer division )
      if n%2 == 0:
         n = n//2 
      # if n is not even then using the following formula
      else:
         n = n*3 + 1 
# calling the function to execute the operation that we wrote before
sequence(10)

Gives the following output:

10
5
16
8
4
2

I recommend you to learn python by following a YouTube video first and then get along with the syntax as you go through. Best of luck!
