''' Purpose: construct list of n base 2 digits for a user-supplied n
'''

import random # want random values, then we need the random module

# get the number of wanted bits
reply = input( 'How many bits: ' )

n = int( reply )

print()
                                
# create an empty list of n bits

bits = []                  # start off with an empty list

# add n random 0/1's to bits

for i in range( 0, n ) :   # i is the iterator, loop will repeat n times

    # each iteration want to add another bit to the list of bits

    # get the next bit

    bit = random.randrange( 0, 2 ) #range from zero up to but not including 2
    bit = random.choice( [0, 1] ) #need to give it a list, so you can create the
    #list prior to calling on choice or put the list within the brackets
    # append the bit to the list of bits so far

    bits.append( bit )  #sticks the digit on the end of the list

#print bits

    print(bits) #when you have a print statement in a loop, it will print what
    #the list currently contains every time the loop runs
    #if you put the print statement outside of the loop, it will just print the
    #final product of the list
