Write a program which repeatedly reads numbers until the user enters “done”. Once “done” is entered, print out the total, count, and average of the numbers. If the user enters anything other than a number, detect their mistake using try and except and print an error message and skip to the next number.

How To Write a program in Python that asks user to input 5 lines of numbers. Your program should represent these lines as a table.

Write a program in Python that asks user to input 5 lines of numbers. Your program should represent these lines as a table.

#function that checks if n is float or not
def float_or_not(n):
    for char in n:
        if char == ".":
            return True

table = []

for i in range(5):
    numbers = input("Enter some numbers: ").split(" ")
    for x, y in enumerate(numbers):
        if float_or_not(y) == True:
            numbers[x] = float(y)
        else:
            numbers[x] = int(y)
    table.append(numbers)

print(table)

Write a function average() that takes no input but requests that the user enters a sentence, i.e. a string. Your function should return the average length of a word in the sentence.

Write a function average() that takes no input but requests that the user enters a sentence, i.e. a string. Your function should return the average length of a word in the sentence.

Usage:
>>> average()
Enter a sentence: Most modern calendars mar the sweet
simplicity of our lives by reminding us that each day
that passes is the anniversary of some perfectly
uninteresting event
5.115384615384615

So far I have this:

def average():
    wordCount = input('Enter a sentence: ')
    sum = 0
    if wordCount != 0:
        average = sum / wordCount
    else:
        average = 0
    return(average)

Write a function that reads the words in words.txt and stores them as keys in a dictionary. It doesn’t matter what the values are. Then you can use the in operator as a fast way to check whether a string is in the dictionary.
