Write a function to find the product (multiplication) of two given numbers only using addition. For example, multiple(2, 5) should result in 10.
Write a function that calculates the modulo (remainder - usually %) of a number divided by another number without using your language's modulo operator itself or your language's division (or multiplication) operator. For example, mod(137, 10) should result in 7 and mod(15, 4) should result in 3.
Write a program to calculate the sum of the digits of the provided number using a loop. For example, sumOfDigits(25) should result in 7 and sumOfDigits(624) should result in 12.
Write a program to find those numbers which are divisible by 7 and of 5, between 1500 and 2700 inclusive.
(challenge) Make this program generic to handle:
- The user setting the valid range
- The user passing in any amount of numbers to check the divisibility (not just 2)
Write a program to find the value of a given number raised to the power of a second given number using a loop. For example, power(5, 2) should result in 25.
Write a function to find the factorial value of any number using a loop. For example, given 4 return 24, given 5 return 120.
Write a program that takes a list of numbers as its input. Then return the highest and lowest numbers that were given.
Sometimes you will need to prompt users for input. This is practice for that!
Don't worry too much about the interface - focus on the logic part. If you're not sure how to get user input using the language that you've chosen feel free to ask in the UnderdogDevs Slack or your mentor!
Write a program that calculates the total cost of a restaurant bill. It should act like the example below. For invalid items, let the user know it is not valid and don’t include it in the total.
Choose from the following menu to order. When finished ordering, submit an empty entry.
Menu:
Burger: $9.50
Vegan Burger: $11.00
Hot Dog: $5.00
Cheese Dog: $7.00
Fries: $5.00
Cheese Fries: $6.00
Cold Pressed Juice: $7.00
Cold Brew: $3.00
Water: $2.00
Soda: $2.00
Enter a food item: burger
Enter a food item: fries
Enter a food item: ice cream
Sorry, “ice cream” is not a valid option
Enter a food item: soda
Enter a food item:
Your total cost is: $16.50
Write a program that prompts users for the number of weeks that they worked. Then prompt them for how many hours they worked each week. Then prompt them for whether they’d like the total number of hours worked or the average of the number of hours per week and return the result asked for.
Example 1:
Number of weeks to track: 3
Week 0 HW Hours: 3
Week 1 HW Hours: 7
Week 2 HW Hours: 10
Enter T for total hours, A for average hours per week: A
6.7 hours
Example 2:
$ python3 hours.py
Number of weeks taking CS50: 2
Week 0 HW Hours: 2
Week 1 HW Hours: 8
Enter T for total hours, A for average hours per week: T
10.0 hours
Write a program that replaces all of the following letters with the corresponding numbers (ignoring case):
lbecomes1abecomes6ebecomes3ibecomes1obecomes0tbecomes7
For example, leetSpeaK becomes 1337SP36K and hello WORLD becomes h3110 W0R1D.
Write a program to check whether the provided string has at least one lower case letter, one upper case letter, one number and one symbol. It should let the user know what they are missing if they are missing something and let them know if it’s valid or if it’s invalid.
The purpose of these questions is to make sure you're comfortable reading and writing data to files from Python, in addition to parsing data of different formats and using different data formats intelligently to create better solutions.
Write a program to ingest the home_data.csv file and list the 10 least expensive houses along with their ZIP codes, condition, and living square feet.
Write a program to ingest the olympics.csv file and list the top 3 countries who have won the most summer olympic medals and the top 3 countries who have won the most winter olypmic medals.
Write a program to ingest the movies.csv file and list top rated movie in each genre.
Write a program to ingest the narcos.json file and list the TV show name, the genres that it fits under, and the average show rating.
Write a program to ingest the narcos.json file and list each episodes' name, season, and rating, sorted by the highest to lowest rating.
