Как получить частоту каждого элемента в списке Python
# easiest way to count the frequency of all elements in a list
lst = ['Sam', 'Sam', 'Tim', 'Tim', 'Tim', 'r', 'l']
freq = {} # stores the frequency of elements
counting = [freq.update({x: lst.count(x)}) for x in lst]
# output of freq
{'Sam': 2, 'Tim': 3, 'r': 1, 'l': 1}

#Note: if you print "counting" it will return a list full of None so ignore it.
