python array methods code example

Example 1: list methods python

list.append(x) # append x to end of list
list.extend(iterable) # append all elements of iterable to list
list.insert(i, x) # insert x at index i
list.remove(x) # remove first occurance of x from list
list.pop([i]) # pop element at index i (defaults to end of list)
list.clear() # delete all elements from the list
list.index(x[, start[, end]]) # return index of element x
list.count(x) # return number of occurances of x in list
list.reverse() # reverse elements of list in-place (no return)
list.sort(key=None, reverse=False) # sort list in-place
list.copy() # return a shallow copy of the list

Example 2: python arrays

array = [1,2,3,4,5]
print(array,array[0],array[1],array[2],array[3],array[4]

#Output#
#[1,2,3,4,5] 1 2 3 4 5

Example 3: python array

array = ["1st", "2nd", "3rd"];
#prints: ['1st', '2nd', '3rd']

Example 4: array in array python

#You can put multiple arrays in one array
tests = [[1,2,3],["r",22,33]]
#prints: [[1,2,3],['r',22,33]]
