Python a way to filter specific chars between letters and not numbers

Question

I have a string:

"|Antigua|and|Barbuda|19|0|2|0|0|17|1|194|20|40|408|North|America|"

And I need to change it to:

"|Antigua and Barbuda|19|0|2|0|0|17|1|194|20|40|408|North America|"

How can I do that to multiple lines?

Can you be more specific about what you want? It seems as though you'd like to remove periods between two alphabetic characters. Is that the only specification? — Josh Clark, Apr 10 '20 at 18:01

str = 'A.b 1.2.3 c.D'
new_str = ''
i = 0  # Keep track of where we are in the string

while i < len(str) - 2:  # Don't look past the end of the string

    # Do the next 3 characters follow the rule?
    if str[i].isalpha() and str[i + 1] == '.' and str[i + 2].isalpha():
        new_str += str[i:i + 3]
        i = i + 3

    # The next 3 characters don't follow the rule, so just take this one
    else: 
        new_str += str[i]
        i += 1

new_str += str[i:len(str)]  # Add on whatever we didn't get in the loop

print(new_str)

s1 = "|Antigua|and|Barbuda|19|0|2|0|0|17|1|194|20|40|408|North|America|"
s2 = "|Gulf|of|Mexico|19|0|2|0|0|17|1|194|20|40|408|North|America|"
s3 = "|Yucatan|Peninsula|19|0|2|0|0|17|1|194|20|40|408|North|America|"

s4 = "|Antigua|and|Barbuda|19|0|2|0|0|17|1|194|20|40|408|North|America|"
s5 = "|Gulf|of|Mexico|19|0|2|0|0|17|1|194|20|40|408|North|America|"
s6 = "|Yucatan|Peninsula|19|0|2|0|0|17|1|194|20|40|408|North|America|"

s_list = [s1, s2, s3]
s_list_2 = [s4, s5, s6]

def len_till_num(*args):
    for arg in args:  # for each list
        for a in arg:  # for each element in list
            i = 0  # set original index position
            while i < len(a) - 2:  # taken from other answer, not to go pass string len
                if a[i].isnumeric():  # check if current index is numeric
                    bad_str = a[1:i - 1]  # if so, assign slice and strip outside '|'s
                    good_char = bad_str.replace('|', ' ')  # assign replacement char
                    a = a.replace(bad_str, good_char)  # replace each element slice
                    i += 1  # reset original index position
                    print(a)
                    break
                else:
                    i += 1  # keep resetting original index position


len_till_num(s_list, s_list_2)

Result:

|Antigua and Barbuda|19|0|2|0|0|17|1|194|20|40|408|North|America|
|Gulf of Mexico|19|0|2|0|0|17|1|194|20|40|408|North|America|
|Yucatan Peninsula|19|0|2|0|0|17|1|194|20|40|408|North|America|
|Antigua and Barbuda|19|0|2|0|0|17|1|194|20|40|408|North|America|
|Gulf of Mexico|19|0|2|0|0|17|1|194|20|40|408|North|America|
|Yucatan Peninsula|19|0|2|0|0|17|1|194|20|40|408|North|America|
