Question

Please help me write a script in python that counts the percentage of each number that appears in the total number of lines, for example 16 appears 2 times out of 16 lines, etc. I got this so far, just dont know how to identify each number and calculate each percentage

with open('itemNumber.txt') as f:
lines = f.readlines()
f.close()

for line in lines:
for item in line.split():
itemCounts[item] += 1

--------itemset.txt-------

16 14 3 28 10
10 9 43 34 24
25 18 15 46 48
16 14 3 28 10
10 9 43 34 24
25 18 15 46 48

with open('itemNumber.txt') as f:
    lines = f.readlines()
    f.close()
    itemCounts = {}
    total = 0
    for line in lines:
        for item in line.split():
            if item not in itemCounts:
                itemCounts[item] = 0
            itemCounts[item] += 1
        total += 1
    print("Number", "Percentage")
    for k, v in itemCounts.items():
        p = (v*100)/total
        print(k, '\t', p)
