Write a function named "freq(1) that takes a list 'I' of numbers and returns a tuple of the most frequent number and its frequency. For example, "freq([1,2,3,4,5,2,3,4,5,3,4,5,4,5,4]) returns (4,5) because number 4 appears 5 times in this list. If multiple numbers appear as most frequent, then the first element of the returned tuple is a list of all those numbers. For example,

Define a function named check_game_finished (encrypted_list) which takes a list of characters as a parameter. The function returns True if the game is over, and False otherwise. The game is over when there is no longer any "*" characters in the parameter list. For example: Test Result False True data = ['h', '*', ¹*¹, ¹*¹, ¹*'] print(check_game_finished (data)) data = ['h', 'e', '1', '1', 'o'] print(check_game_finished(data)) data = ['s', ¹*¹ 'd'] False print(check_game_finished (data))
Create a function that returns the characters from a list or string ron odd or even positions, depending on the specifiers. The specifier will be "odd" for items on odd positions (1, 3, 5, ...) and "even" for items on even positions (2, 4, 6, ...). Examples char_at_pos([2, 4, 6, 8, 10], "even") [4, 8] # 4 & 8 occupy the 2nd & 4th positions - char_at_pos ("EDABIT", "odd") "EAI" # "E", "A" and "I" occupy the 1st, 3rd and 5th positions char_at_pos(["A", "R", "B", "I", "T", "R", "A", "R", "I", "L",
Define a function named display_word (encrypted_list) which takes a list of characters as a parameter. The function prints the parameter list as shown in the examples below. Note: you can assume that the parameter list is not empty. For example: Test Result **¹, ¹*¹'] GUESS THE WORD: h**** data = ['h', '*', '*', display_word (data) ''*', '*', '*'] GUESS THE WORD: s****** data = ['s', '*', display_word (data)
Write a function called match_words() that takes three input parameters; a list of strings of any length (e.g., ['789', 'del','a', 'do', ‘abc’,'bb','dcc']), a character c and an integer x. This function returns a list of all strings in the 2-D list that starts with the character c and is at most x characters long. Sample run, >>> alist = ['6789', 'black', 'green', 'd', 'blue', 'red', 'beige', 'dddd', 'yellow', 'buff', 'zzzzzzzzz'] >>> print( match_words( alist, ‘b’, 4 )) ['blue’, ‘buff’]
Question 2: Write a function that takes a string as its only argument and returns a sorted list of characters used in the string. The resulting list should only contain lower case letters and each letter should exist only once. Also, the resulting list shouldn't contain any spaces or punctuation marks, such as ",;.!?". For example, strletters ("We are, the Champions!") returns ['a', 'c', 'e', 'h', 'i', 'm', 'n', 'o', 'p', 'r', 's', 't', 'w'] def strletters(istr):
In program problem5.py, write a function named sums that takes 3 arguments: 2 lists of integers nums1 and nums 2, and an integer target; then return a tuple containing indices i and j of the two numbers in nums 1 and nums 2, respectively, where the numbers at that indices add up to target (i.e, nums1 [i] + num2[j] = target). If there is no solution, return "Not found". The function sums must contain exactly only one loop (either a for-loop or a while-loop), otherwise you will get no point. A nested-loop is considered as more than one loop. You can assume that each given input either have exactly one solution or none. Below is the code of the main function in problem5.py, complete the program by writing the function sums. Note that the values of nums 1, nums2 and target are given in the main function which can be changed in the code. This program does not take any input. if name __main__': nums1 = [11, 2, 15, 7, 8] nums2 = [3, 4, 5] target = 9 print(sums(nums 1, nums2, target)) Example…
Write a function called find_duplicates which accepts one list as a parameter. This function needs to sort through the list passed to it and find values that are duplicated in the list. The duplicated values should be compiled into another list which the function will return. No matter how many times a word is duplicated, it should only be added once to the duplicates list. NB: Only write the function. Do not call it. For example: Test Result random_words = ("remember","snakes","nappy","rough","dusty","judicious","brainy","shop","light","straw","quickest", "adventurous","yielding","grandiose","replace","fat","wipe","happy","brainy","shop","light","straw", "quickest","adventurous","yielding","grandiose","motion","gaudy","precede","medical","park","flowers", "noiseless","blade","hanging","whistle","event","slip") print(find_duplicates(sorted(random_words))) ['adventurous', 'brainy', 'grandiose', 'light', 'quickest', 'shop', 'straw', 'yielding']…

Write a function named 'freq(I) that takes a list 'I' of numbers and returns a tuple of the most frequent number and its frequency. For example, "freq([1,2,3,4,5,2,3,4,5,3,4,5,4,5,4]) returns (4,5) because number 4 appears 5 times in this list. If multiple numbers appear as most frequent, then the first element of the returned tuple is a list of all those numbers. For example, freq([1,2,3,1,2,1,2,3,1,2]) will return ([1,2], 4) because both 1 and 2 appear 4 times in the list. def freq(1): # remove the following line to solve this question return
Can someone please explain to me ASAP???!!!!
Define a function named get_encrypted_list (word) which takes a word as a parameter. The function returns a list of characters. The first element is the first letter from the parameter word and the rest is as a sequence of '*', each '*' representing a letter in the parameter word. Note: you can assume that the parameter word is not empty. For example: Test Result ['h', ¹*¹ **', '*'] *** guess = get_encrypted_list('hello') print (guess) print (type (guess)) guess = get_encrypted_list('succeed') ['s', '*', print (guess) **']
Write a function named 'freq(I)` that takes a list 'I' of numbers and returns a tuple of the most frequent number and its frequency. For example, "freq([1,2,3,4,5,2,3,4,5,3,4,5,4,5,4]) returns (4,5) because number 4 appears 5 times in this list. If multiple numbers appear as most frequent, then the first element of the returned tuple is a list of all those numbers. For example, freq([1,2,3,1,2,1,2,3,1,2]) will return ([1,2], 4) because both 1 and 2 appear 4 times in the list. def freq(l): # remove the following line to solve this question return
