Introduction to Python — Session 7
In this session we cover:
- What are functions and why we use them
- Creating your own functions
- DRY Principle
- Calling functions
- Returning values from Functions
Write your code
- Write a function that prints your name
- Write a function that accepts a name as a parameter and prints "Hello, name"
- Loop through the list ["Alice", "Bob", "Charlie"] and call the function you just wrote
- Write a function that prints the area of two passed in parameters
- Write a function called 'print_list' that accepts a list as a parameter and then prints out each item of the list
- Put the following into a function that accepts age as a parameter:
- If they are younger than 11, print "You're too young to go to this school"
- If they are between 11 and 16, print "You can can come to this school"
- If they are over 16, print 'You're too old for school"
- If they are 0, print "You're not born yet!"
- Write a function called is_odd that will return True or False if the integer passed as a parameter is odd (hint: x % 2 will return true for all odd numbers)
- Write a function that accepts a word and returns it backwards, e.g. 'hello' to 'olleh'
- Write a recursive function that accepts a number and prints that number of stars, followed by ever decreasing stars on each line, E.g:
***** **** *** ** *
- Create a padlock function. You need to be able to pass in a passcode and if its correct it should return "Unlock", else "Locked"
- Write a function that returns the sum of multiples of 3 and 5 between 0 and limit (parameter). For example, if limit is 20, it should return the sum of 3, 5, 6, 9, 10, 12, 15, 18, 20
- Write a function called is_prime() that accepts a number and return True or False if the number of prime or not
- Write a function that checks to see if a string is a palindrome, if it is, it will return True and False if it is not.
- Write a function that checks to see if a sentence is a palindrome, if it is, it will return True and False if it is not. Tip - you may want to format your sentence so it is all lower case, and .replace() to get rid of white spaces.
