Python Lists

-
  A List is a collection of different kinds of values or items. Since Python lists are mutable, we can change their elements after forming. Below given are some of the programs using Python Lists: list1 = [1, 2, "Python", "Program", 15.9] list2 = ["Amy", "Ryan", "Henry", "Emma"] # printing the list print(list1) print(list2) # printing the type of list print(type(list1)) print(type(list2)) ----------------------------------------------------------------------------------------------------------------------------- a = [ 1, 2, "Ram", 3.50, "Rahul", 5, 6] b = [ 1, 2, "Ram", 3.50, "Rahul", 5, 6] a == b --------------------------------------------------------------------------------------------------------------------------- list = [1,2,3,4,5,6,7] print(list[0]) print(list[1]) print(list[2]) print(list[3]) # Slicing the elements print(list[0:6]) # B...

Break Statements

-
  The break is a keyword in python which is used to bring the program control out of the loop. The break statement breaks the loops one by one, i.e., in the case of nested loops, it breaks the inner loop first and then proceeds to outer loops. Break is used to abort the current execution of the program and the control goes to the next line after the loop. Below given are some of the break statements in Python: my_list = [1, 2, 3, 4] count = 1 for item in my_list: if item == 4: print("Item matched") count += 1 break print("Found at location", count) ---------------------------------------------------------------------------------------------------------------------------- my_str = "python" for char in my_str: if char == 'o': break print(char)  ----------------------------------------------------------------------------------------------------------------------- i = 0; while 1: print(i...

Continue Statements

-
  In Python  continue  statement  is used to skip the rest of the code inside a loop for the current iteration and proceed to the next iteration immediately. It is particularly useful when certain conditions need to be bypassed without breaking the entire loop. Below given are some of the python programs using Continue statements: for num in range(1, 11): if num % 2 == 0: continue # Skip the rest of the loop for even numbers print(num) ----------------------------------------------------------------------------------------------------------------------------- for i in "Python Programming": # skipping the character equal to 'o' if i == 'o': continue # printing the characters print(i, end='') ----------------------------------------------------------------------------------------------------------------------------- numbers = [10, -3, 5, -8, 7] # iterating through the elements of the list for i in numbers: # ...

Python Loop Statements

-
  2 Types of loops in python: 1) For Loop: It is designed to repeatedly execute a code block while iterating through a list, tuple, dictionary, or other iterable objects of Python. string = "Python" # Initiating a loop for s in a string: # giving a condition in if block if s == "o": print("If block") # if condition is not satisfied then else block will be executed else: print(s) ---------------------------------------------------------------------------------------------------------------------------- numbers = [3, 5, 23, 6, 5, 1, 2, 9, 8] # initializing a variable that will store the sum sum_ = 0 # using for loop to iterate over the list for num in numbers: sum_ = sum_ + num ** 2 print("The sum of squares is: ", sum_) ----------------------------------------------------------------------------------------------------------------------------- my_list = [3, 5, 6, 8, 4] for iter_var in ra...

Python If Else Statement

-
  Three types of If statement: 1) If Statement    num = int(input("enter the number:"))    if num%2 == 0:       print("The Given number is an even number") Program to print the largest of the three numbers.    a = int (input("Enter a: ")); b = int (input("Enter b: ")); c = int (input("Enter c: ")); if a>b and a>c:   print ("From the above three numbers given a is largest");   if b>a and b>c:   print ("From the above three numbers given b is largest");   if c>a and c>b:   print ("From the above three numbers given c is largest");   2) If- else statement:   age = int (input("Enter your age: "))   if age>=18:      print("You are eligible to vote !!"); else:      print("Sorry! you have to wait !!"); 3)Elif Statement:      number = int(input("Enter the number?")) if number==10:    print("The given numb...

Python Strings

-
  Python string is the collection of the characters surrounded by single quotes, double quotes, or triple quotes. #Using single quotes str1 = 'Hello Python' print(str1) #Using double quotes str2 = "Hello Python" print(str2) #Using triple quotes str3 = '''''Triple quotes are generally used for represent the multiline or docstring''' print(str3) String Indexing # Given String str = "PYTHONSTRING" # Start Oth index to end print(str[0:]) # Starts 1th index to 4th index print(str[1:5]) # Starts 2nd index to 3rd index print(str[2:4]) # Starts 0th to 2nd index print(str[:3]) #Starts 4th to 6th index print(str[4:7]) str = 'PYTHONSTRING' print(str[-1]) print(str[-3]) print(str[-2:]) print(str[-4:-1]) print(str[-7:-2]) # Reversing the given string print(str[::-1]) print(str[-12]) Reassigning Strings str = "HELLO" str[0] = "h" print(str) str = "HELLO...

  In this video we will see how to run python programs in MS Visual Studio Code.  Please watch this video and let me know in the comments section if you have any questions. Please do like, share and subscribe my youtube channel for more such videos. https://www.youtube.com/watch?v=iW1VHVXCILA Cheet Sheet: 👇 Type Casting   What is type casting? Type casting, on a very basic level, is the method involved with changing the information kind of a variable.   v     Fuction used in type casting: int(): Converts a worth to a whole number. float(): Converts a worth to a drifting point number. str(): Converts a worth to a string. bool(): Converts a worth to a boolean. v   Examples of implicit type casting:   program1: a = 2.5 b = 3 + 4j result = a + b print(result) program2: num = 10 message = "The value of num is: " + str(num) print(message) Examples of explicit type casting: Program1:          num_float = 3.1...
