When it is required to check if a date is valid or not, and print the incremented date if it is a valid date, the ‘if’ condition is used.Below is a demonstration of the same −Example Live Demomy_date = input("Enter a date : ") dd, mm, yy = my_date.split('/') dd=int(dd) mm=int(mm) yy=int(yy) if(mm==1 or mm==3 or mm==5 or mm==7 or mm==8 or mm==10 or mm==12):    max_val = 31 elif(mm==4 or mm==6 or mm==9 or mm==11):    max_val = 30 elif(yy%4==0 and yy%100!=0 or yy%400==0):    max_val = 29 else:    max_val = 28 if(mm12 or dd max_val):    print("The date ...

When it is required to read a number and print the pattern of summation of natural numbers, a simple ‘for’ loop can be used.Below is a demonstration of the same −Example Live Demomy_num = int(input("Enter a number... ")) for j in range(1,my_num+1):    my_list=[]    for i in range(1,j+1):       print(i,sep=" ",end=" ")       if(i

When it is required to display the sum all the natural numbers within a given range, a method can be defined that uses a loop to iterate over the elements, and returns the sum of these numbers as output.Below is a demonstration of the same −Example Live Demodef sum_natural_nums(val):    my_sum = 0    for i in range(1, val + 1):       my_sum += i * (i + 1) / 2    return my_sum val = 9 print("The value is ") print(val) print("The sum of natural numbers upto 9 is : ") print(sum_natural_nums(val))OutputThe value is 9 The sum ...

When it is required to print all the elements which can’t be divided by 2 or 3 and lie between 1 and 50, the constraints are mentioned in the form of a ‘while’ loop and ‘if’ condition.Below is a demonstration of the same −Example Live Demoprint("Integers not divisible by 2 and 3, that lie between 1 and 50 are : ") n = 1 while n

When it is required to find the smallest divisor of a an integer, a simple ‘for’ loop is used.Below is a demonstration of the same −Example Live Demofirst_num = int(input("Enter a number...")) my_list = [] print("The number is ") print(first_num) for i in range(2, first_num+1):    if(first_num%i==0):       my_list.append(i) my_list.sort() print("The smallest divisor is : ") print(my_list[0])OutputEnter a number...56 The number is 56 The smallest divisor is : 2ExplanationThe number is taken as an input from the user.An empty list is defined.The number taken from user is displayed on the console.The number range is iterated over.It is ...

When it is required to print all possible combination of digits when the input is taken from the user, nested loop is used.Below is a demonstration of the same −Example Live Demofirst_num = int(input("Enter the first number...")) second_num = int(input("Enter the second number...")) third_num = int(input("Enter the third number...")) my_list = [] print("The first number is ") print(first_num) print("The second number is ") print(second_num) print("The third number is ") print(third_num) my_list.append(first_num) my_list.append(second_num) my_list.append(third_num) for i in range(0, 3):    for j in range(0, 3):       for k in range(0, 3):          if(i!=j&j!=k&k!=i):     ...

When it is required to read two numbers and print the quotient and remainder when they are divided, the ‘//’ and ‘%’ operators can be used.Below is a demonstration of the same −Example Live Demofirst_num = int(input("Enter the first number...")) second_num = int(input("Enter the second number...")) print("The first number is ") print(first_num) print("The second number is ") print(second_num) quotient_val = first_num//second_num remainder_val = first_num%second_num print("The quotient is :") print(quotient_val) print("The remainder is :") print(remainder_val)OutputEnter the first number...44 Enter the second number...56 The first number is 44 The second number is 56 The quotient is : 0 The remainder is : ...

When it is required to print all the elements in a given range that is divisible by a specific number, a simple for loop can be used.Below is a demonstration of the same −Example Live Demolower_num = int(input("Enter lower range limit...")) upper_num = int(input("Enter upper range limit...")) div_num = int(input("Enter the number that should be divided by...")) for i in range(lower_num, upper_num+1):    if(i%div_num==0):       print(i)OutputEnter lower range limit...3 Enter upper range limit...8 Enter the number that should be divided by...2 4 6 8ExplanationThe upper and lower range of numbers is taken as input from the user.The number by ...

When it is required to take a number and compute a specific pattern, the value of n is taken from the user. Next, two variables are assigned this specific pattern and their sum is calculated.Below is a demonstration of the same −Example Live Demomy_input = int(input("Enter a value for n...")) temp_val = str(my_input) t_1=temp_val+temp_val t_2=temp_val+temp_val+temp_val my_result = my_input+int(t_1)+int(t_2) print("The computed value is : ") print(my_result)OutputEnter a value for n...4 The computed value is : 492ExplanationAn input from the user is taken.It is converted into a string and assigned to a variable.The value of ‘n*n’ and the value of ‘n*n*n’ is calculated.Their ...

When it is required to sort the elements of an array in descending order, the ‘sort’ method can be used by specifying a parameter named ‘reverse’ to True.Below is a demonstration of the same −Example Live Demomy_list = [44, 56, 42, 31, 11, 23, 78, 89, 9, 0] print("The list is :") print(my_list) my_list.sort(reverse = True) print("The list after sorting is :") print(my_list)OutputThe list is : [44, 56, 42, 31, 11, 23, 78, 89, 9, 0] The list after sorting is : [89, 78, 56, 44, 42, 31, 23, 11, 9, 0]ExplanationA list is defined, and is displayed on the console.The ...
