How to declare an array in Python?

Question

How can I declare an array in Python?

I could not find any reference to arrays in the documentation.

Answer 1

Here are the examples to create and basic in-built functions to handle and alter the array:

array_name = []  #to declare an empty array

array_1 = [ '2', '3', '4', '7', '9'] #to declare an array with numericals

print( "First Element:", array_1 [0]) #returns the first element of an array

print( "Last Element:", array_1 [-1]) #returns the last element of an array

print( "Length of the array:", len(array_1)) #returns length of an array

Array is mutable i.e. can modify after declaring variable. There are a lot of in-built libraries like append(), insert(), etc. to alter the array.
