Write a function named encode_string(sentence) that takes a string value as its input and returns an encoded string, where each character of the input string is replaced by its ASC code plus 3 values. Whitespace characters should not be encoded. For example, if the function was passed the input string: Hello world then it should return: Khoor Zruog For example: Test sentence "Hello World print(encode_string(sentence)) Result Khoor Zruog

Write a function that accepts a string as an argument and returns true if the argument ends with the substring .doc'. Otherwise, the function should return false

Write a function called lower_concat(string1, string2) that receives two strings as parameters. The function must convert these two strings to lowercase, concatenate them and print the new string. pls solve using python language

python Please Write a function that finds the number of occurrences of a specified character in a string using the following header: def count(str, c) ex: count("welcome", "e") returns 2.

Can you use Python programming language to to this question? Thanks

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

Complete the rotate_text() function that takes 2 parameters, a string data and an integer n. If n is positive, then the function will shift all the characters in data forward by n positions, with characters at the end of the string being moved to the start of the string. If n is 0 then the text remains the same. For example: rotate_text('abcde', rotate_text('abcde', rotate_text('abcde', 1) would return the string 'eabcd' 3) would return the string 'cdeab' 5) would return the string 'abcde' rotate_text('abcde', 6) would return the string 'eabcd' ... and so on. If n is negative, then the function will shift the characters in data backward by n positions, with characters at the start of the string being moved to the end of the string. For example: rotate text('abcde', -1) would return the string 'bcdea'

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...
