PYTHON PROGRAM THAT ASKS THE USER TO ENTER TWO STRINGS OF SAME LENGTH AND WILL ALTERNATE THE CHARACTERS OF THE TWO STRINGS.FOR EXAMPLE: abcde and ABCDE THEN THE PROGRAM WILL PRINT AaBbCcDdEe

Write a program that asks the user to enter two strings of the same length. The program should then   check  to see if the strings are of the same length. If they are not, the program should print an appropriate   message and exit. If they are of the same length, the program should alternate the characters of the two   strings. For example, if the user enters abcde and ABCDE the program should print out AaBbCcDdEe.


CODE:

def alternate_string(s1,s2):

    new_string=""

    if len(s1)==len(s2):

        print("The two strings are of same length")

        for i in range(len(s1)):

            new_string=new_string+s2[i]+s1[i]

    else:

        print("The two strings are not of same length")

    return new_string

string1=input("Enter string-1:")

string2=input("Enter string-2:")

print("New string is:",alternate_string(string1,string2))


EXPLANATION:

In this program we have defined a function named alternate_string which accepts two strings as parameters.

In this function, we have created an empty string(new_string="").And using len() function we check the length of two strings.

If they are equal then, it will add the characters of the two strings alternately to the new_string using for loop.

The function will return the new_string.

If the length of two strings is not equal then the program will print an appropriate message.

Next we have to call the function by passing two strings as parameters.

PYTHON PROGRAM THAT USES FOR LOOP TO PRINT THE NUMBERS 8,11,14,17,20,.........,83,86,89

Image
  Write a program that uses a for loop to print the numbers 8, 11, 14, 17, 20, . . . , 83, 86, 89. SYNTAX OF FOR LOOP:  for iterator_var in sequence:         statement(s) It can be used to iterate over a range and iterators. RANGE() FUNCTION: The range() function returns a sequence of numbers, starting from 0 by default, increments by 1 by default and stops before a specified number. SYNTAX OF RANGE() FUNCTION: range(start value,stop value,step count) EXAMPLE: range(5) --->0,1,2,3,4  ;  range(1,5) ---> 1,2,3,4 ; range(1,7,2) --->1,1+2=3,3+2=5 -->1,3,5   CODE: for i in range(8,90,3):     print(i,end=",") EXPLANATION: In this code the loop iterates over a range(8,90,3) i.e.,it prints 8 and then increments the value by 3. It will continue this process until it reaches 89. In the print statement end="," indicates that each number will be separated by comma in the output. OUTPUT:

PYTHON PROGRAM THAT ASKS USER FOR LARGE INTEGERS AND INSERTS COMMAS INTO IT ACCORDING TO THE STANDARD AMERICAN CONVENTION FOR COMMAS IN LARGE NUMBERS

Image
 Write a program that asks the user for a large integer and inserts commas into it according to the  standard American convention for commas in large numbers. For instance, if the user enters 1000000, the output should be 1,000,000 CODE: n=int(input("Enter a number:")) print("The number seperated with commas is:{:,}".format(n)) EXPLANATION: The  format()  method formats the specified value(s) and insert them inside the string's placeholder. The placeholder is defined using curly brackets: {} Inside the placeholders you can add a formatting type to format the result SYNTAX: string .format( value1, value2... ) PARAMETER VALUES: Parameter Description value1, value2... Required. One or more values that should be formatted and inserted in the string. The values can be A number specifying the position of the element you want to remove. The values are either a list of values separated by commas, a key=value list, or a combination of both. The values can be of any data
