Write a function that finds the number of occurrences of a specified character in a string using the following header:def count(s, ch):The str class has the count method. Implement your method without using the count method. For example, count("Welcome", 'e') returns 2. Write a test program that prompts the user to enter a string followed by a character and displays the number of occurrences of the character in the string.
the string below comes from an alphabet consisting of only characters A and B. Accordingly,
write the full code of the program (Use the given space below the question. If you struggle to fit
then upload a file) that prints the permutation list that can be formed with the
characters A or B, which can replace the question marks, into a text file. (Hint: give a go to

- You can check whether a string is a substring of another string by using the find method in the str class. Write your own function to implementfind. Write a program that prompts the user to enter two strings and then checks whether the first string is a substring of the second string.arrow_forwardFinally, complete the following programming task on https://play.kotlinlang.org and submit your link to Blackboard. The input should be a string declared at the top of the file. We are given strings containing brackets of 4 types - round (), square [], curly {} and angle ones. The goal is to check, whether brackets are in correct sequence. I.e. any opening bracket should have closing bracket of the same type somewhere further by the string, and bracket pairs should not overlap, though they could be nested: here square and curly brackets are nested in the (a+[b*c] - {d/3}) round ones (a+[b*c) 17] does not make sense Input data will contain a test-case in form of a character sequence. Answer should contain 1 (if bracket order is correct) or 0 (if incorrect) for each of test- cases, separated by spaces. Example: input data: (a+[b*c]-{d/3}) * here square brackets overlap with round ones which (a + [b c) (((a * x) + [b] y) + c auf (zlo)men [gy] four {s} answer: 1 0 0 1 17] *arrow_forwardString replacement is read from input. Then, sentence is read from input. If replacement is in sentence, then: Output 'Located at index: ' followed by the index of the last occurrence. Create a string from sentence with the first two occurrences of replacement replaced by '5' and output sentence on a newline.arrow_forward
- Write a program that reads 10,000 words into an array of strings. The program will then read a second file that contains an undetermined number of words and search the first array for each word. The program will then report the number of words in the second list that were found on the first list. Read the 10,000 words from the "List of 10000 Random Words" text file into an array of strings. Then read the words from the "Search Words" text file, one at a time, and search for them in the array. Report the count of the number of words found.arrow_forwardWrite a program that reads a sentence and store it in an array of characters. The program also reads a word and store in it a string variable. The program then conceals the word in the sentence with the character @'. Sample input / output: Enter a sentence: The town in which we live is a green town and big Enter a word: town Result: The @aa@ in which we live is a green @@@@ _and bigarrow_forwardWrite a program that reads words from a file (filename given as a string parameter) and prints the occurance of each word(case insensitive). And print the words in alphabetical order. For example, if the file contains text Love is free free is love then the function should print free:2 is:2 love:2 def count_word(filename): # YOUR CODE HERE raise NotImplementedError()arrow_forward

Print the string in the output.arrow_forwardWrite a program to read the date and average from the temps.txt file. Use a string data type for the date and a double for the average. The program should then convert the average (Fahrenheit) to Celsius. The conversion formula is subtract 32 from the average (Fahrenheit) and then multiply by five and divide by nine, e.g., (average –32) * 5 / 9. Output the date, the average temperature (Fahrenheit) and the Celsius temperature to a file named celsius.txt. Use the manipulators you have learned about in this chapter to format the output as shown in the sample below and print each number value to one decimal space. 1. Identify the following parameters to complete the specification above. Input parameters? Output parameters? Constant parameters? 2. Attach the input and output of a successful execution of your program below (Hint:Use the snipping tool to take screenshots):arrow_forwardWrite a program that reads all words from a file and saves them in a data structure.

Hint: Make a very long string "January February March ...", in which you add spaces such that each month name has the same length. Then use substring to extract the month you want.arrow_forwardWrite a program to read the date and average from the temps.txt file. Use a string data type for the date and a doub e average.

They are in the format of A1A 1A1, where A could be any letter and 1 could be any number from 0-9. Given an unsorted list of postal codes, write a Python program, in a file call postal.py, to sort the list of postal codes (actually modify the given list into a sorted list) and then display the sorted postal codes such that each postal code with the same starting letter is printed on the same line, with each line in alphabetical order. Note that the postal codes can be in any order on the same line, as long as they all start with the same letter, or you can have them sorted on the line as well. For example, given the following list of postal codes: postal_codes = ['A1A 1A1', 'B3K 5X5', 'V9A 7N2', 'A0Z 6P7', 'H0H 0H0', 'A1B 1T0'] The output would be similar to: Sorted postal codes: A0Z 6P7 A1A 1A1 A1B 1T0 B3K 5X5 H0H 0H0 V9A 7N2 Note: You are not permitted to use the sort() method.arrow_forward
