Max Function

Statistical function is of many categories. One of them is a MAX function. The MAX function returns the largest value from the list of arguments passed to it. MAX function always ignores the empty cells when performing the calculation.

Power Function

A power function is a type of single-term function. Its definition states that it is a variable containing a base value raised to a constant value acting as an exponent. This variable may also have a coefficient. For instance, the area of a circle can be given as:

Question

(1) Prompt the user for a string that contains two strings separated by a comma. (1 pt)
Examples of strings that can be accepted:
o Jill, Allen
o Jill, Allen
• Jill, Allen
Ex:
Enter input string: Jill, Allen
(2) Report an error if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains
a comma, then assume that the input also contains two strings. (2 pts)
Ex:
Enter input string: Jill Allen
Error: No comma in string
Enter input string: Jill, Allen
(3) Extract the two words from the input string and remove any spaces. Store the strings in two separate variables and output the strings.
(2 pts)
Ex:
Enter input string: Jill, Allen
First word: Jill
Second word: Allen
(4) Using a loop, extend the program to handle multiple lines of input. Continue until the user enters q to quit. (2 pts)
Ex:
Enter input string: Jill, Allen
First word: Jill
Second word: Allen
Enter input string: Golden Monkey
First word: Golden
Second word: Monkey

(1) Prompt the user to enter a string of their choosing. Store the text in a string. Output the string. Ex: Enter a sample text: We'll continue our quest in space. There will be more shuttle flights and more shuttle crews and, yes, more volunteers, more civilians, more teachers in space. Nothing ends here; our hopes and our journeys continue! You entered: We'll continue our quest in space. There will be more shuttle flights and more shuttle crews and, yes, more volunteers, more civilians, more teachers in space.

Aim: Read a string, S and print its integer value. If S cannot be converted to an integer, print Bad String. ''' # getting the input S = input().strip() try: # if it's possible to convert the entered string into an integer then this block will execute print(int(S)) except: # if it's not possible, then this block will be executed print('Bad String') ''' COMPLEXITY: Time Complexity -> O(1) Space Complexity -> O(1) Sample Input 1: 3 Sample Output 1: 3 Sample Input 2: SB Sample Output 2: Bad String Explaination: '3' as a string can be converted into the integer 3, whereas SB can't be converted to an integer hence the 'except' block is executed and 'Bad String' is printed.
