Write a function called word_count() that accepts a string as a parameter and returns an integer value representing the number of words in the string.  A word may be separated by a space or tab (" ", "/t"), assume no other punctuation will be in the string.  Write a main() function to demonstrate how it works. In python

hideshow Write a function hideshow that accepts two string arguments, an input string and a masking string. The masking string is a string consisting of '0's and '1's that has the same length as the input string. The function then returns a new string that is the same as the input string, except that it is masked. That is, in any position where the masking string contains a '0' the input character is replaced by a '#', whereas if the masking string contains a '1', the character is unchanged. Sample usage: >>> hideshow('apple', '11001') 'ap##e' >>> hideshow('apple', '00000') '#####' >>> hideshow('apple', '11111') 'apple' >>> hideshow('abcdefghijklmnopqrstuvwxyz', 13*'01') '#b#d#f#h#j#1#n#p#r#t#v#x#z' >>> hideshow 'df###re##', '101010101' ) 'd#####e##' >>> hideshow( 'df###re%%', '101010101' )=='d#####e##' True

Using Python write a string-comparison function named strNcompare that compares up to n characters of a string s1 with the other string s2. The function must return 0, -1, or 1 if the first n-character portion of s1 is equal to, less than, or greater than the corresponding first n-character portion of s2, respectively. (1) You must use the following function definition: def strNcompare(s1, s2, n): (2) String comparison must be case-insensitive. For example, the strNcompare function must return 0 for the s1 value of ‘tommy’ and the s2 value of ‘TOMMY’. (3) You should not use a loop such as the while loop and the for loop inside the strNcompare function.    Then write a Python program that receives two words and the number of characters for comparison, calls the strNcompare function, and then shows the result. Your program keeps doing this until the user enters the value of -1.     Your program displays the message ‘String comparison [1(play), -1(quit)]: ’ and receives the value 1 or -1…

An 'expression' in programming is... * O any code that performs an operation using a single operator. O any code that is written on a single line. O any code that evaluates to a singular value. any code that calls a function.
