- Write a program that takes in a string from the user and stores it in a variable called 'word, and an integer which is stored in a variable called number: 1) Make sure that the number entered is in fact an integer 2) If the word has at least number amount of vowels then print the number(th) vowel. Otherwise print "Sorry this word only has X vowels. where X is the number of vowels in the word.arrow_forwardWrite a Python program that declares a string and returns key-value pairs of the letters in alphabetical order which occur in the string together with the number of times each letter occurs. Case should be ignored.arrow_forwardWrite a python program to read input a string and replace all occurrences of the first character of the string with '_'. Testcase: "restart" Expected output: _esta_tarrow_forward
- Using sys module in Python. Create a program, longest.py, that has a function that takes one string argument and prints a sentence indicating the longest word in that string. If there is more than one word print only the first. Your print statement should read: The longest word is x Where x = the longest word. The word (x) should be all lowercase.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. 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. 32) * 5/9. Output the date, the average temperature (Fahrenheit) and the Celsius temperature to a file named celsi Use the manipulators you have learned about in this chapter to format the output as shown in the sample be low 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_forwardUsing Python, use import sys Create a program, longest.py, that has a function that takes one string argument and prints a sentence indicating the longest word in that string. If there is more than one word print only the first. Your print statement should read: The longest word is x Where x = the longest word. The word should be all lowercase.arrow_forward
- Write a Python program which asks the user for a series of strings as input, and stores each entered string. The user signals the end of input by typing quit. Please implement the following: text_get() This function does the job of repeatedly asking the user for text to input. Before the function finishes, it must combines all the strings entered into one string, and return that string. main() The only purpose of this function is to call text_get() and print the returned string. Do not use the eval function.arrow_forwardWrite a program that takes a capitalized character string (with letters ‘A’ through ‘Z’) and returns a lower-case character string. Begin with the values of r0 and r1 containing 0x46554C4C and 0x4D4F4F4E, which represent the ASCII characters of “FULL” and “MOON”, respectively. You should put the lower-case versions of these hexadecimal values in r2 and r3.arrow_forward3 – Write a python program that prompt the user to enter a string and count the number of words and characters in that string without using built-in methods.arrow_forward
