Python please... Implement a function printIndex() that takes a list as a parameter, prompts the user to enter a whole number n, and prints the element in position Index[n]. If the list is empty ([]) or n is not a valid index into the list, the function will not print anything. Be careful to do the correct thing with negative indices. You should assume that the user will enter a whole number when prompted, and the function will crash if the user does not enter an integer. The function should not change the list passed as a parameter. Hint: Just because this involves a list does not mean that you need a loop to solve the problem. Think carefully about the right construct to use here. The following shows the function template, and several examples runs of the function (you must show all the examples with these values in your submission): Template def printIndex(lst): replace with your docstring newList = lst # ________________________ elementNum =…
In Python Use the Design Recipe to write a function round_list, which consumes two arguments, a list of floats (float_list), and the other a positive integer (decimals). The return value is the same as float_list, but with each element in the list rounded to decimals decimal places. Your function should NOT modify the original list. Include a docstring!
Assume that L is a list of Boolean values, True and False. Write a program in python with a function longestFalse(L) which returns a tuple (start, end) representing the start and end indices of the longest run of False values in L. If there is a tie, then return the first such run. For example, if L is False False True False False False False True True False False 0 1 2 3 4 5 6 7 8 9 10 then the function would return (3, 6), since the longest run of False is from 3 to 6.
In Python Use the Design Recipe to write a function has_duplicates, which consumes a list and returns True if the list has any duplicate entries, False otherwise. Your function should return False if the list is empty
Code in python Given a list, L, the function front_two creates a new list of length 2 out of the first two items in L as follows: In the new list, the second item becomes the first item, and the first item becomes the second. If L contains only one item, the first item in the new list should be the value None. If L is empty, both items in the new list should be value None. The function returns the new list. For example: Test Result L = ['a', 'b', 'c', 'd'] print(front_two(L)) ['b', 'a'] L = [] print(front_two(L)) [None, None] L = [5, 2] print(front_two(L)) [2, 5] L = [7] print(front_two(L)) [None, 7]
python codeWrite a Python function listDictPrime() that gets as parameter a list of integers, creates and returns a dictionary where keys are the integers of the list and values are either "prime" or "not prime" depending on key being prime number. Assume that there is a function isprime() that gets an integer parameter and returns True if the integer is a prime number, and returns False if not. Use function call to this function. Do not write this function. Example: if parameter list is [4, 7, 2, 6, 3], then the returned dictionary will be {4: "not prime", 7: "prime", 2: "prime", 6: "not prime", 3: "prime"}. Write only the function listDictPrime().
In Python, A. Write a function that accepts a list of integers as an argument and prints the list's numbers after deleting any odd numbers. Call the function from the main program. This list will be used by the main program. Sample Output: num = [1,6,7,8,-4, 120, -20, 25, 44, 20, 27] B. Create a function that takes the list above, removes duplicates, and produces a new list that is duplicate-free. To test your function using this list, write a main program. num = [5,25,15,25,5,2,17,12,27,2,12] Answer = [5, 25, 15, 2, 17, 12, 27]
PYTHON CODEWrite a function removeRange() that takes a list of integer numbers and two integer numbers as parameters, returns a new list where the numbers between the 2nd and 3rd parameters (both inclusive) are removed from the 1st list. Assume 2nd parameter is less than the 3rd parameter.
code in python The function print_reverse takes one parameter, L, which is a list. The function then prints the items in the list in reverse order, one item per line, WITHOUT changing the value of L. Write the function definition. Note 1: This function does NOT get anything from standard input. Note 2: This function DOES, however, print to standard output. Note 3: You should NOT return anything from this function (let it return None by default). Hint: Some ideas for iterating over a list in reverse order are given here. For example: Test Result L = ['apple', 'banana', 'cherry'] Lcopy = L[:] return_value = print_reverse(L) if return_value != None or L != Lcopy: print("Error") cherry banana apple L = ['happy'] Lcopy = L[:] return_value = print_reverse(L) if return_value != None or L != Lcopy: print("Error") happy L = [] Lcopy = L[:] return_value = print_reverse(L) if return_value != None or L != Lcopy: print("Error")
Because floating-point numbers are imprecise, it is common to compute data values of type float that are very close but not exactly equal to the value 0.0. a) In Python, Write a function countNZdata that counts number of elements in a list of type float whose absolute value is less than or equal to a positive tolerance parameter. The function takes the list as its first parameter; the second parameter is the positive float value that is the tolerance. Function should return the number of data values that meet this criterion. For example, for the given list: [2.19, -0.04, 1.66, 0.05, 4.70, -6.53, -0.11, -1.07, 1.94, -2.23] and a tolerance = 0.1, the function should return the value 3. b) Demonstrate that the function works by inputting different example values.
# Create a list of tuplestuples = [("p", 1), ("q", 2), ("r", 3)]# Use enumerate() to iterate over the tuples and print the index and valuefor index, value in enumerate(tuples):print(index, value)This code will print the following output:0 p1 q2 r Could you try to modify your code to get the output mentioned by you? Also, the output for the above function should be0 ('p', 1)1 ('q', 2)2 ('r', 3) Could you please confirm?
In python, create a function wherein you transfer elements from a list into different lists. If a certain element has been encountered, continue the listing in a new list. Continue doing so until this certain element has been encountered two times. Disregard the succeeding elements after the second certain element. Once you have your 2 lists, return them both as a tuple. Example: element_stop = ‘a’ original_list = [‘b’, ‘c’, ‘d’, ‘d’, ‘f’, ‘a’, ‘e’, ‘t’, ‘d’, ‘g’, ‘f’, ‘t’, ‘a’, ‘b’, ‘e’] The output should be: ([‘b’, ‘c’, ‘d’, ‘d’, ‘f’], [‘e’, ‘t’, ‘d’, ‘g’, ‘f’, ‘t’])
