How to check a value in a list value range in python

I have a value to check in the list range

Example:

    recipies = int(input("enter:"))
print(recipies)
interval =[]
for i in range(recipies):
    x = (input().split())
    interval.append(x)
print(interval)
agroup =int(input("enter:"))
print(agroup)
qali = []
for i in range(agroup):
    x = (input().split())
    qali.append(x)
print(qali)
for cmp in qali:
    toa = cmp[1:]

Input:
4
1 4
3 10
2 6
5 8
3
1 5
2 2 6
3 1 10 9

Output:
3
4
2

Here i want to check weather the value of toa available in the interval if available i want to print how many times that value available in the given intervals,same way i want to check values in quali(list)
