This article is an extension of the ‘Make a list’ chapter of Python. If you need to learn basics then visit the Python course first. You can also practice a good number of questions from practice section.
append
Appends list with an item or adds an item at the end of the list.
a = [1, 2, 3,] a.append(4) # a --> [1, 2, ,3 4]
count
Counts the number of times an element is appearing in a list.
a = [1, 2, 3, 2, 2]
a.count(2) # 3
extend
Adds a list to another list
a = [1, 2, 3]
b = [4, 5]
a.extend(b) # a --> [1 ,2, 3, 4, 5]
index
Gives the index of the first appearance of an element in a list.
a = [1, 2, 2, 3]
a.index(2) # 1
insert
Inserts an element at a given position
a = [1, 2, 3, 4]
a.insert(1,5) # a --> [1, 5, 2, 3, 4]
max
Gives an element which has the maximum value.
a = [1, 2, 3, 4, 56, 9]
max(a) #56
min
Gives an element which has the minimum value.
a = [1, 2, 3, 4, 56, 9]
min(a) #1
pop
Removes and returns an element at a given position. If no position is specified then it removes and returns the last element.
a = [1, 2, 3, 4, 5, 6]
a.pop(1) # 2
a.pop() # 6
remove
Removes the first element whose value is matched with the given value.
a = [1, 2, 3]
a.remove(1) # a --> [2, 3]
reverse
Reverses a list.
a = [1, 2, 3, 4]
a.reverse() # a --> [4, 3, 2, 1]
sort
Arranges the elements of a list in ascending order.
a = [3, 4, 1, 2]
a.sort() # a --> [1, 2, 3, 4]
