def count_digits(text: str) -> int:
total=0 #initialize counter variable
for l in text: #for each of the characters in the text
if l.isdigit(): #check if the character is a digit
total+=1 #if so, increase the counter
return total
if __name__ == '__main__':
print("Example:")
print(count_digits('hi'))
# These "asserts" are used for self-checking and not for an auto-testing
assert count_digits('hi') == 0
assert count_digits('who is 1st here') == 1
assert count_digits('my numbers is 2') == 1
assert count_digits('This picture is an oil on canvas '
'painting by Danish artist Anna '
