How can I count elements of a list within a certain range?

Question:

i need to calculate how much numbers form string got value higher or equal to 25 and lower or equal to 50

numbers = [25, 24, 26, 45, 25, 23, 50, 51]

#  'count' should be 5 
count = 0

# I need to filter all numbers and only numbers what are higher than 25 can stay 

numbers = [25, 24, 26, 45, 25, 23, 50, 51]

#  'filtered' should be equal to [26, 45, 50, 51]
filtered = []

Answers:

numbers = [25, 24, 26, 45, 25, 23, 50, 51]
count = len(numbers)
filtered = [num for num in numbers if 25 < num <= 50]
count -= len(filtered)

This should help

numbers = [25, 24, 26, 45, 25, 23, 50, 51]
count=0
f=[]
for i in numbers:
    if i>=25 and i<=50:
        f.append(i)
        count+=1
print(f)

you can use the built-in function filter:

numbers = [25, 24, 26, 45, 25, 23, 50, 51]
filtred = list(filter(lambda x : x > 25, numbers))
# [26, 45, 50, 51]

how much numbers form string got value higher or equal to 25 and lower
or equal to 50

you can use the built-in function sum:

count = sum(1 for e in numbers if e >= 25 and e<= 50)
# 5

A simple way to do it would be to create an empty list, iterate through the current list and append all relevant items to the new list, like so:

numbers = [25, 24, 26, 45, 25, 23, 50, 51]
new_list =[]

for i in numbers:
    if i>=25 and i<=50:
        new_list.append(i)

print(new_list)
