How does the Evaluate Formula dialog box help fix errors?

Modify the program you wrote for Chapter 6 Exercise 6 so it handles the following

Basile [38]

Answer:

#try except

try:

#opening the file

read_file = open('numbers.txt', 'r')

#Store the numbers in the variable file_numbers.

file_numbers = read_file.read()

#close the file

read_file.close()

#Split the number of files in list_values.

list_values = file_numbers.split()

#how many numbers are there

list_length = len(list_values)

try:

#loop it up

for i in range(list_length):

list_values[i] = float(list_values[i])

#Add up all the numbers, put into list_sum

List_sum = sum(list_values)

#heres how we average it

Average_value = (List_sum)/list_length

#print

print(Average_value)

except ValueError:

print( "File must have only numbers. Try again." )

#handles IOError exceptions

except IOError:

#Display statement

print("Trouble opening file. Try again.")

Explanation:

The python program uses the try-except exception handling method to catch errors in the code. The IOError is used for catching input and output errors in the program like file handling while the ValueError keyword in the except statement is used to catch data type errors from a return statement, calculation or user input.

Write a program that asks the user for the speed of a vehicle (in miles per hour) and how many hours it has traveled. It should

HACTEHA [7]

Answer:

speed = float(input("Enter the speed: "))

hours = int(input("Enter the hours: "))

distance = 0

for i in range(hours):

distance += speed * 1

print("The distance after " + str(i+1) + ". hour(s): " + str(distance))

Explanation:

*The code is in Python.

Ask the user to enter the speed and the hours

Initialize the distance as 0

Create a for loop that iterates hours times. Inside the loop, calculate the cumulative distance traveled at the end of each hour and print it (Note that the distance = speed x hour)

Anna71 [15]

Answer:

The program in Python is as follows:

import collections

from collections import Counter

from itertools import groupby

import statistics

str_input = input("Enter a series of numbers separated by space: ")

num_input = str_input.split(" ")

numList = []

for num in num_input:

if(num.lstrip('-').isdigit()):

if num[0] == "-" or int(num)>10:

print(num," is out of bound - rejecting")

else:

print(num," is valid - accepting")

numList.append(int(num))

else:

print(num," is not a number")

print("Largest number: ",max(numList))

print("Smallest number: ",min(numList))

print("Range: ",(max(numList) - min(numList)))

print("Mode: ",end = " ")

freqs = groupby(Counter(numList).most_common(), lambda x:x[1])

print([val for val,count in next(freqs)[1]])

count_freq = {}

count_freq = collections.Counter(numList)

for item in count_freq:

print(item, end = " ")

lent= int(count_freq[item])

for i in range(lent):

print("#",end=" ")

print()

Explanation:

See attachment for program source file where comments are used as explanation. (Lines that begin with # are comments)

The frequency polygon is printed using #'s to represent the frequency of each list element
