# Solutions


l = ['apple', 'banana', 'orange', 'kiwi', 'grapes']

v = ['potato', 'tomato', 'onion', 'capsicum', 'beans']

l.extend(v)

print(l)

l.append('brinjal')

print(l)

l.remove('capsicum')

print(l)

m = [i for i in l if not i.startswith('b')]

print(m)

l.remove('apple')
l.remove('potato')

print(l)

l.pop(3)

print(l)

l.reverse()

print(l)

l.sort()

print(l)

l.clear()

print(l)

del l

# 12: remove() takes the item value. pop() takes the item index.

# 13

l = ['apple', 'banana', 'orange', 'kiwi', 'grapes']
print('apple' in l)

# 14: append() adds an element. extend() does the concatenation of two lists.
