Reversing a List in Python

scottalanmiller

Simple list reversal using a for loop and the pop and append functions. This empties the original list as it goes. So you end up with only a single list at the end.

months = ['January', 'February', 'March', 'April', 'May', 'June', 'July',
          'August', 'September', 'October', 'November', 'December']
newMonths = []

monthlen = len(months)
for i in range(0,monthlen):
    month = months.pop()
    newMonths.append(month)


print(newMonths)

And here is a similar one but this time, both lists remain...

months = ['January', 'February', 'March', 'April', 'May', 'June', 'July',
          'August', 'September', 'October', 'November', 'December']
newMonths = []

monthlen = len(months)
for i in range((monthlen - 1),-1,-1):
    month = months[i]
    newMonths.append(month)

print(newMonths)
