Dictionary in Python Dictionary is an unordered collection of mutable values indexed by unique keys. Values in a dictionary can be of any datatype, mutable and can be duplicated, whereas keys can’t be repeated and are immutable. Dictionaries are just like map(), storing, and retrieving elements by referencing a key. As dictionaries are referenced by … Read more
Python Program to check if a tuple and a list are identical tuple = (9, 8, 7, 6, 5) list = [9, 8, 7, 6, 5] #using loop flag1 = True for i in range(0, len(tuple)): if tuple[i] != list[i]: flag1 = False break if flag1: print(f”{tuple} and {list} are identical”) else: print(f”{tuple} and {list} … Read more
Python program to remove duplicates from a list list1 = [2, 6, 9, 8, 4, 8, 6, 6, 5, 7, 2, 4] #using list comprehension list2 = [] [list2.append(ele) for ele in list1 if ele not in list2] print(list2) #Output: [2, 6, 9, 8, 4, 5, 7] #using list comprehension and enumerate() list3 = [ele … Read more
Python program to move Word to Rear-end str1 = “Beta Python: Python for U ” word = “Python” #using slicing and find() str2 = str1[:str1.find(word)] + str1[str1.find(word) + len(word):] + word print(str2) #Output: Beta : Python for U Python #using replace() str3 = str1.replace(word,””) + word print(str3) #Output: Beta : for U Python Slicing extracts … Read more
Python program to find the minimum and maximum value in a list of tuples tuple_list = [(6, 5), (3, 8), (1, 6), (4, 7), (3, 1)] ele1 = tuple(map(max, zip(*tuple_list))) ele2 = tuple(map(min, zip(*tuple_list))) print(ele1, el2) #Output: (6, 8) (1, 1) The built-in max() function returns the largest element in an iterable. The built-in min() … Read more

Python Program to split a string into groups of n consecutive characters string = “Beta Python: Python for U” n = 5 split_string = [(string[ch:ch+n]) for ch in range(0, len(string), n)] #list comprehension print(split_string) #Output: [‘Beta ‘, ‘Pytho’, ‘n: Py’, ‘thon ‘, ‘for U’] List comprehension is a compact method that defines a list and … Read more
Python program to copy a list list1 = [9, 4, 10, 5] list2 = list(list1) print(“Original list: “,list1) print(“Copied list: “,list2) #Output: Original list: [9, 4, 10, 5] Copied list: [9, 4, 10, 5] The list() built-in method takes an iterable and creates a new list of its elements. Python program to concatenate multiple lists … Read more
Indexing “Indexing” means addressing an element of a sequential object by its position within the sequential object. A sequential object is in general, an ordered collection. In python, every element of an ordered collection is accessed based on their position in the collection. An index is a numerical form of position. Python uses square bracket … Read more
