python, repeat random.randint?

I am new to python and i would like to know how to make the code to repeat the random.randint part 100 times.

#head's or tail's

print("you filp a coin it lands on...")

import random

heads = 0
tails = 0


head_tail =random.randint(1, 2,)

if head_tail == 1:
    print("\nThe coin landed on heads")
else:
    print("\nThe coin landed on tails")

if head_tail == 1:
    heads += 1
else:
   tails += 1

flip = 0
while True :
    flip +=1
    if flip > 100:
        break



print("""\nThe coin has been fliped 100 times
it landed on heads""", heads, """times and tails""", tails,
"""times""")

input("Press the enter key to exit")

I'm new in Python and generally in programming, but I created my own code base on 1 day programming practice. Coin flip coding exercise is one of the first from the book I study now. I tried to find solution on the internet and I found this topic.

I was aware to use any code from this topic because few functions used in previous answers were not familiar to me.

To anyone in similar situation: Please feel free to use my code.

import random

attempts_no = 0
heads = 0
tails = 0

input("Tap any key to flip the coin 100 times")


while attempts_no != 100:
 number = random.randint(1, 2)
 attempts_no +=1
 print(number)
 if number == 1:
    heads +=1
 elif number ==2:
    tails +=1

print("The coin landed on heads", heads, "times")
print("The coin landed on heads", tails, "times")

You could do it all in one line with a list comprehension:

flips = [random.randint(1, 2) for i in range(100)]

And count the number of heads/tails like this:

heads = flips.count(1)
tails = flips.count(2)

Or better yet:

num_flips = 100
flips = [random.randint(0, 1) for _ in xrange(num_flips)]
heads = sum(flips)
tails = num_flips - heads

First of all, I would replace that while loop with:

for flip in xrange(100):
  ...

Secondly, to conduct 100 random trials, move the randint() call -- as well as everything else that you want to perform 100 times -- inside the body of the loop:

for flip in xrange(100):
  head_tail = random.randint(1, 2)
  ...

Finally, here is how I would do the whole thing:

heads = sum(random.randint(0, 1) for flip in xrange(100))
tails = 100 - heads

You would use range(100), since you're on Python3.x which creates a list from 0 to 99 (100 items). It'll look something like this:

print("you flip a coin it lands on...")

import random

heads = 0
tails = 0


for i in xrange(100):
    head_tail = random.randint((1, 2))

    if head_tail == 1:
        print("\nThe coin landed on heads")
    else:
        print("\nThe coin landed on tails")

    if head_tail == 1:
        heads += 1
    else:
        tails += 1    


print("""\nThe coin has been fliped 100 times
it landed on heads""", heads, """times and tails""", tails,
"""times""")

input("Press the enter key to exit")
