Lists in Python are versatile knowledge constructions that keep the order of components, which means that gadgets are saved in a particular sequence. They’ll include any kind of object, together with numbers, strings, and even different lists, permitting for nesting to any depth. This implies you possibly can have lists inside lists, creating complicated knowledge constructions. Parts inside a listing may be accessed utilizing their index positions, ranging from zero. Lists are mutable, so their contents may be modified after creation — gadgets may be added, eliminated, or modified. Moreover, lists are dynamic, which means their dimension can change as components are added or eliminated. This flexibility makes lists a robust and generally used device in Python programming.
# Creating a listing with blended knowledge varieties: string, integer, and one other integer
nlis = ['python', 25, 2022]
# Show the listing
print(nlis) # Output: ['python', 25, 2022]
==============================================================================
Output:
['python', 25, 2022]
# Show constructive and unfavorable indexing of every factor within the listing 'nlis'
# Print constructive and unfavorable indexing of the primary factor
print('Optimistic and unfavorable indexing of the primary factor: n - Optimistic index:', nlis[0], 'n - Damaging index:', nlis[-3])
print()
# Print constructive and unfavorable indexing of the second…
