Occurrences using FOR and IF cycle

2. Your code works well

a = [100, 100, 50, 20, 100, 30]
x = 100
c = 0
for i in range(len(a)):
    if x == a[i]:
        c = c + 1

print(c)
>>> 3

YOUR code works well because you replaced the x = input("Insert number: ") with x = 100.
HIS code doesn´t work because the input function returns a string and not an integer value.
So the code must be edited into x = int(input("Insert number: "))
