for loop - Python code with a "string" input that removes #comment but not if it's a string (or it's like this 'blabla #comment blabla' it's not to be removed)

Question

It's my first question first I have the wrong attempt that only works without weird people putting # inside a string inside a string.

Below is my attempt to do this but doesn't work. Please help me.

Is there a way to use split as it beautifully works in 2 lines without the # in "" or '' condition? Or should one just develop this while loop function bellow (last function)?... At least we would be expecting input/txt to not have both this 'string' and this "string" but if you can make it work for these mixed up and even """"strings"""" or these ''strings''. It would really help me learn as a beginner.

#def remove_cpp_com(txt):
    #    n_text=txt.split("#")
    #    return n_text[0]
    
    #This is the wrong attempt that only works without weird people putting # inside a string inside a string.
    
    #Bellow is my attempt to do this but doesn't work. Please help me.
    
    def remove_py_com(txt):
        i=0
        endproduct=""
        subgroup_number=len(txt.split("'"))
        other_subgroup_number=len(txt.split('"'))
        for i in txt:
            if i not in "'" or i not in '"':   # meaning if txt[i]!="'"  string in this string
                no_symbol_output=txt.split("#")
                endproduct+=no_symbol_output[0] 
    # no "  or ' > by splitting in '#' which removes it and returning first index should work...
                return endproduct
            elif i in'"' and other_subgroup_number>2:
                    false_string_comment=txt.split('"')
                    last_index_string=list(txt[-1])
                    tails_first_item, tails_last_item =last_index_string.split("#")[0,-1]
                    endproduct+='"'+strg(false_string_comment)+'"'+strg(tails_first_item)
                    return endproduct
            else:
                    other_false_string_comment=txt.spit("'")
                    endproduct+="'"+strg(also_false_string_comment)+"'"+strg(tails_first_item)
                    return endproduct
        return endproduct
    

#Only while loop works for this?

    def remove_py_com(txt):
        line = ""
        i = 0
        while i < len(txt):
            if txt[i] == "#":
                    return line
                line += txt[i]
                i += 1
                if txt[i-1] == '"':
                    while i < len(txt):
                    line += txt[i]
                    i += 1
                    if txt[i-1] == '"':
                        break
        return line
