Exercise 50

Write a python program as a function which takes a string s as a parameter and returns the list of numeric characters contained in the string s. Example if s = 'Python 3.0, released in 2008, and completely revised in 2020' the function returns the list: [3, 0, 2, 0, 0, 8, 2, 0, 2, 0].

Solution

def extractNumbers(s):
    # initializing extracted list numbers
    L = []

    for x in s:
        if x.isnumeric():
            x = int(x)
            L.append(x)
    return L
s = 'Python 3.0, released in 2008, and completely revised in 2020'
print(extractNumbers(s))
# The output is : [3, 0, 2, 0, 0, 8, 2, 0, 2, 0]
