Suppose, your friend is building an automated car called “Besla”. He needs to fix the programming of the car so that it runs at a proper speed. Now, write a python program that takes 2 inputs (distance in meters and time in seconds). The program should then print the velocity in kilometers per hour of that car. Also, it should print whether the car is working properly based on the following chart.

Velocity

Information to be printed

Less than 60 km/h

Too slow. Needs more changes.

Between 60 km/h to 90 km/h

Velocity is okay. The car is ready!

Greater than 90 km/h

Too fast. Only a few changes should suffice.

Mean ,Median and Mode

Given a list of integers,write a program to print the mean,median,and mode.

Mean-The average value of all the numbers

Median- The mid point value in the second list.

Mode-the most common value in the list.if multiple elements with same frequency are present ,print all the values with same frequency in increasing order.

INPUT:

The Input will be a single line containing space-seperated integers.

OUTPUT:

The First line of output should contain the mean,round off the value to 2 decimal places.

The Second line of output should contain the medium,round off the value to 2 decimal places.

The third line of output should contain the mode.

Mean should always be a float value.

Median should be a float value when there are even number of elements. otherwise should be an integer value.

See sample Input?Output for the output format.

INPUT

2 2 2 3 4 4 5 5 6 7 8 8

Sample Output 1

Mean: 4.67

Median: 4.5

Mode: 2

Sample Input 2

2 6 3 1 8 12 2 9 10 3 4

Sample Output 2

Mean: 5.45

Median: 4

Mode: 2 3

Family List:

A list of words is called the Family if the words in the list follow the following rule.

we should be able to obtain each word in the list by

-changing exactly one letter from the previous word in the list

Given a list of words ,determine if the list is a Family or Not a Family

input:

The first line of input is an integer T representing the number of test cases

the first line of each test case has an integer N representing the total number of words

The second line contains N space separated strings

INPUT:

Write a program that reads several lines of text from a text file named “data.txt” and prints a table indicating the number of one-

letter words, two-letter words, three-letter words, etc. appearing in the text. For example, if the text file contains Whether ‘tis nobler in the mind to suffer the output should be:

Word Length. Occurrences

1 0

2 2

3 2

4 2 (including ‘tis)

5 0

6 2

7 1

Make a list contain any 4 names and also using for loop to print this list and please print the last string in the list

A number is Expensive if the number of digits of its prime factorization (including exponents greater than 1) is greater than the total digits of the number itself. Given an integer Implement a function that returns a string: If the number of digits of the prime factorization (including exponents greater than 1) is equal to the number of digits of N print Equal If the number of digits of the prime factorization (including exponents greater than 1) is lower than the number of digits of N print Cheap print None of the above if none of the two above conditions is true
