How can I get a list with m tails? Python

So I need to create a list with m tails. The elements of the list will be a random choice between tail and head. I did like :

Def S(m):
    list=[]
    counter=0
    signs=["head","tail"]
    while counter<(m):
        list.append(random.choice(signs))
        for k in list:
            if k=="tail":
               counter+=1
    print(list)

So this one gives me a list but not with m tails. I think the while is wrong here but I am not sure how to write the code. Can you help me to change it?

Solution

  • this will work:

    from random import choice

def S(m):
    lst = []
    counter = 0
    signs = ["head", "tail"]
    while counter < m:
        toss = choice(signs)
        lst.append(toss)
        if toss == 'tail':
            counter += 1
    return lst

lst = S(10)
print(lst)                # ['head', 'tail', 'head', 'head', 'tail', ...]
print(lst.count('tail'))  # 10
