Printing Names using for loop

Question

president = [('D. Trump',2017), ('Barack Obama',2009), ('B. Clinton',1993), 
             ('George W. Bush',2001)]

max_w = president[0][1]
min_w = president[0][1]

for word in president:

    if word[1] > max_w:
        max_w = word
    elif word[1] < min_w:
        min_w = word   

print(max_w, min_w)

why the max_w and min_w is a tuple? should it be a int??

Answer 1

I think you want max_w = word[1] and min_w = word[1] within those conditionals.

Alternatively, you could write this:

for name, year in president:
    if year > max_w:
        max_w = year
    if year < min_w:
        min_w = year

Or save the initialization and do this (even better IMO):

max_w = max(year for name, year in president)
min_w = min(year for name, year in president)
