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

import random # want random values, then we need the random module
# this is greyed out because we haven't used it yet. once we use a function from random, this will look normal

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

n = int( reply )

print()
                                
# create an empty list of 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

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

    # get the next bit

    bit = random.randrange( 2 ) # give me either a 0 or a 1
    # other ways:
        # bit = random.randrange( 0, 2 )
        # bit = random.choice( [ 0, 1 ] )
        # bit = random.choice( "01" ) <- for this one, we'd have to cast the bit to an int
    # append the bit to the list of bits so far

    bits.append( bit ) # add the newly generated random bit to the list

# print bits 
print( bits )
