10Days of Python A Challenge A Day

Day 1

Task 1

Write a function called divide_or_square that takes one argument (a number), and returns the square root of the number if it is divisible by 5, returns its remainder if it is not divisible by 5. For example, if you pass 10 as an argument, then your function should return 3.16 as the square root.

Task 2

Write a function called longest_value that takes a dictionary as an argument and returns the first longest value of the dictionary. For example, the following dictionary should return – apple as the longest value.

Day 2

Task 1

Write a function called convert_add that takes a list of strings as an argument and converts it to integers and sums the list. For example [‘1’, ‘3’, ‘5’] should be converted to [1, 3, 5] and summed to 9.

Task 2

Write a function called check_duplicates that takes a list of strings as an argument. The function should check if the list has any duplicates. If there are duplicates, the function should return the duplicates. If there are no duplicates, the function should return "No duplicates". For example, the list of fruits below should return apple as a duplicate and list of names should return "no duplicates".

Day 3

Task 1

Write a function called register_check that checks how many students are in school. The function takes a dictionary as a parameter. If the student is in school, the dictionary says ‘yes’. If the student is not in school, the dictionary says ‘no’. Your function should return the number of students in school. Use the dictionary below. Your function should return 3.

Task 2

You are given a list of names above. This list is made up of names of lowercase and uppercase letters. Your task is to write a code that will return a tuple of all the names in the list that have only lowercase letters. Your tuple should have names sorted alphabetically in descending order.

Day 4

Task 1

Write a function called only_floats, which takes two parameters a and b, and returns 2 if both arguments are floats, returns 1 if only one argument is a float, and returns 0 if neither argument is a float. If you pass (12.1, 23) as an argument, your function should return a 1.

Task 2

Write a function called word_index that takes one argument, a list of strings and returns the index of the longest word in the list. If there is no longest word (if all the strings are of the same length), the function should return zero (0). For example, the list below should return 2.

Day 5

Task 1

Create a function called my_discount. The function takes no arguments but asks the user to input the price and the discount (percentage) of the product. Once the user inputs the price and discount, it calculates the price after the discount.The function should return the price after the discount. For example, if the user enters 150 as price and 15% as the discount,your function should return 127.5.

Task 2

You work for a school and your boss wants to know how many female and male students are enrolled in the school. The school has saved the students in a list. Your task is to write a code that will count how many males and females are in the list.

Day 6

Task 1

Write a function called user_name that generates a username from the user’s email. The code should ask the user to input an email and the code should return everything before the @ sign as their user name. For example, if someone enters [email protected], the code should return ben as their username.

Task 2

Write a function called zeroed code that takes a list of numbers as an argument. The code should zero (0) the first and the last number in the list.

Day 7

Task 1

Write a function called string_range that takes a single number and returns a string of its range. The string characters should be separated by dots(.) For example, if you pass 6 as an argument, your function should return ‘0.1.2.3.4.5’.

Task 2

You are given a list of names, and you are asked to write a code that returns all the names that start with ‘S’. Your code should return a dictionary of all the names that start with S and how many times they appear in the dictionary. Here is a list below:

Day 8

Task 1

Write a function called odd_even that has one parameter and takes a list of numbers as an argument. The function returns the difference between the largest even number in the list and the smallest odd number in the list. For example, if you pass [1,2,4,6] as an argument the function should return 6 -1= 5.

Task 2

Write a function called prime_numbers. This function asks a user to enter a number (integer) as an argument and returns a list of all the prime numbers within its range. For example, if user enters 10, your code should return [2, 3, 5, 7] as prime numbers.

Day 9

Task 1

Create a function called biggest_odd that takes a string of numbers and returns the biggest odd number in the list. For example, if you pass ‘23569’ as an argument, your function should return 9. Use list comprehension.

Task 2

Write a function called zeros_last. This function takes a list as argument. If a list has zeros (0), it will move them to the front of the list and maintain the order of the other numbers in the list. If there are no Zeros in the list, the function should return the original list sorted in ascending order. For example, if you pass [1, 4, 6, 0, 7,0,9] as an argument, your code should return [1,4, 6, 7, 9, 0, 0]. If you pass [2, 1, 4, 7, 6] as your argument,your code should return [1, 2, 4, 6, 7].

Day 10

Task 1

Write a function called hide_password that takes no parameters. The function takes an input (a password) from a user and returns a hidden password. For example, if the user enters ‘hello’ as a password the function should return ‘****’ as a password and tell the user that the password is 4 characters long.
