country = ["HUN","MAC","PHL","SVK","USA"] is the list of country codes

LE_1960 = [65.57, 32.33, 70.82, 32.36, 50.55] is the list of the Life Expectancy at Birth of each countries in 1960.

LE_2013 = [75.33, 77.54, 82.28, 80.89, 69.98] is the list of the Life Expectancy at Birth of each countries in 2013

Calculate the percentage improvement in Life Expectancy between 1960 and 2013 for each country and store it as a new list.

Output those countries that achieved 100% or more improvement in LE.

Show two columns along with headings.

Country Code %increase in LE

My answer is added below, but it doesn't work out.

increase = []

alist = []

print("-"*24)

print( "%-12s%12s" % ("Country Code","%increase in LE"))

print("-"*24)

# Calculate the percentage improvement in Life Expectancy between 1960 and 2013 for each country and store it in a new list.

for i in range(len(country)):

increase = ((LE_2013[i]-LE_1960[i]) / LE_1960[i])

alist.append(increase)

# Remove countries whose Life Expectancy is less than 100% and store it in a new list.

for k in range(len(alist)):

if alist[k] < 1:

country_result = country.remove(country[k])

LE_result = alist.remove(k)

print( "%-12s%12.2f" % (country_result, LE_result))
