Problem Q1.4.
[6 pts]
Assume year is an integer representing a year between 2001 and 2399.
Below, complete the if statement so that it tests whether
year represents a leap year.
(Recall that leap years occur when the year is a multiple of 4
but not of 100. You don't need to worry about multiples of
400.)
if
print year, 'is a leap year.'
if year % 4 == 0 and year % 100 != 0:
print year, 'is a leap year.'
Problem Q1.5.
[8 pts]
Complete the program so that it displays the
characters of word in reverse order, one per line.
Below is an illustration of how it should work.
Word? straw
w
a
r
t
s
word = raw_input('Word? ')
word = raw_input('Word? ')
for i in range(len(word)):
print word[len(word) - 1 - i]
Alternative solution:
word = raw_input('Word? ')
for i in range(len(word) - 1, -1, -1):
print word[i]
