Issue

This Content is from Stack Overflow. Question asked by grom

I have to take a string with info about a person in the format LAST, FIRST (BIRTH-DEATH) to first, last, age. i.e. print(biotoage(“Last, First (1912-1954)”)) turns into First Last, 42.

This is the code I currently have:

def bio_to_age(bio: str) -> str:
count = 0
# loop for search each index
for i in range(0, len(bio)):
    # Check each char
    # is comma or not
    if bio[i] == ",":
        count += 0
firstName = bio[0:count]
lastName = bio[count:]
numAge = 2022-1945
return firstName, lastName, numAge

Its not working to count the first and last names, which are case sensitive, and I do not know how to do the year either.

Thank you!

Solution

It’s much easier to do this using the split function. Assuming that there are no extraneous spaces, we could do the following.

def bio_to_age(bio: str) -> str:
    current_yr = 2022
    last,first,yrs = bio.split() # split string by spaces
    last = last[:-1]             # remove comma at end of first segment
    yrs = yrs[1:-1]              # remove lead and closing parentheses
    start,end = yrs.split('-')   # split years segment by "-"
    start = int(start)
    if end == '':                # if no death year is given
        end = current_yr
    else:                        # if death year is given
        end = int(end)
    return f"{first} {last}, {end - start}"

print(bio_to_age("Adle, Leo (1945-)"))
print(bio_to_age("Adle, Leo (1945-2000)"))

The resulting outputs are Leo Adle, 77 and Leo Adle, 55.

Here’s a version that accounts for an optional middle name

def bio_to_age(bio):
    tokens = bio.split() # split string by spaces
    if len(tokens) == 3:
        last,first,yrs = tokens
    else:
        mid,last,first,yrs = tokens 
    last = last[:-1]
    yrs = yrs[1:-1]              # remove lead and closing parentheses
    start,end = yrs.split('-')      # split years segment by "-"
    start = int(start)
    if end == '':
        end = 2022
    else:
        end = int(end)
    if len(tokens) == 3:
        return f"{first} {last}, {end - start}"
    return f"{first} {mid} {last}, {end - start}"

print(bio_to_age("Adle, Leo (1945-)"))
print(bio_to_age("Adle, Leo (1945-2000)"))
print(bio_to_age("Allie Jackie, Allegra (1945-)"))
