yet another homework question

[Fab95]

Thank you for advice! I should simplify my coding

1	for i in range(100):

i'm reading your responses now
it will take me time to answer back

for now
thank you :)

I agree that you should try harder by yourself. Yet I'm learning too and specially trying hard to manage loops. Although I think this exercise was not really hard to solve.

1 2 3 4 5 6 7 8 9 10 11 12 13

import random heads=0 i=0 for i in range(99):   i+= 1   heads_count = random.randrange(2)   if heads_count == 0:     heads_count = 0   elif heads_count == 1:     heads_count = 1     heads+=1   print("Number of heads", heads, ".  Number of tails", 100 - heads)

wait a moment.
thank you
but what if the for loops are only learned a chapter after?

As a beginner myself, I will ask that if you were not yet taught about the for loop until the next chapter, were you taught the while loop already, while True: is a favorite way to repeat something again and again, were you taught how to count and keep a running total for three different items such as heads and tails and total coin tosses, were you taught how to use an if statement, a nested if statement, an elif statement and a break statement after reaching the end of the program? These are the minimum items I can think of without using a for loop. You actually may not need to count tails as total tosses minus heads implies tails. I don't think they want you to copy / paste a simple code 100 times and keep count along the way. Do you know how to import Random, was that taught also? What are your thoughts of the book now?

The while True solution would be the following:

1 2 3 4 5 6 7 8 9 10 11 12 13

import random count=0 heads=0 while count<99:   count+= 1   heads_count = random.randrange(2)   if heads_count == 0:     heads_count = 0   elif heads_count == 1:     heads_count = 1     heads+=1    print("Number of heads", heads, ".  Number of tails", 100 - heads)

To make the code happy as to PEP8 style:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

import random     count = 0 heads = 0 while count < 99:     count += 1     heads_count = random.randrange(2)     if heads_count == 0:         heads_count = 0     elif heads_count == 1:         heads_count = 1         heads += 1   print("Number of heads", heads, ".  Number of tails", 100 - heads)

running pycodestyle on that produces no warnings, (which I named fab95.py)

Does this work?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

import random   # set the coin headsCount, tailsCount, count = 0, 0, 0   # the loop count = 0 while count<100:     coin = random.randrange(2)     if coin == 0:          headsCount += 1     else:         tailsCount += 1     count += 1   print ("The number of heads was", headsCount) print ("The number of tails was", tailsCount)   input("\n\nPress the enter key to exit.")

Simplified, but still using while instead of for

1 2 3 4 5 6 7

from random import randint count, heads = 0, 0 while count < 100:     heads += randint(0, 1)     count += 1 print('Heads', heads) print('Tails', 100 - heads)

var += 1 is the same as var = var + 1 (well, technically, it isn't but you don't need to worry about that here)
