Prequisite: [Tutorial on Functions](https://youtu.be/u-OmVr_fT4s)
## Exercise 1: Grabbing User Input
_💡 Tick the checkboxes (or work packages) as you complete each sub task. Breaking down a task into it's steps is the same as solving 90% of the problem._
Write a function called `grab_int` that:
- [ ] takes a `message` parameter
- [ ] prompts the user for a number
- [ ] returns that value as an `int` _(hint: typecasting)_
- [x] Outside of the function, call the function
- [x] Print out the value
### Example of what the console interaction would look like
_Note: `grab_int` is called with "What is your number?"_
```bash
What is your number?
94
Your number is 94 # Expected result
```
### Complete the code here
```lang-py
def grab_input(message):
print (message)
user_input = input()
return user_input
user_input = grab_input('What is your number?')
print ('Your number is ' + user_input)
```
Done? Congratulations!! 🙌
Now let's knock off Exercise 2.
## Exercise 2: Adding Two Numbers
Let's write a function to add 2 numbers. But this time rather than writing the statements to ask input again we will reuse the `grab_int` function you wrote above.
### Examples of what the console interaction would look like
```bash
Number 1?
21
Number 2?
4
Your result is 25 # Expected result
```
### Complete the code here
```lang-py
def grab_input(message):
print (message)
user_input = input()
return user_input
number1 = grab_input('What is your first number?')
number2 = grab_input('What is your second number?')
def add(x,y):
return int(x) + int(y)
sum = str(add (number1, number2))
print ('Your result is ' + sum)
```
You are awesome 🤩
## Exercise 3: Calculating Sum
Now we do nothing. Seriously. Calculating the sum of two numbers is the same as adding two numbers. All we have to do is write function called `sum` that calls `add`. So basically, calling one function from another function.
Don't worry, you got this.
### Examples of what the console interaction would look like
```bash
Number 1?
21
Number 2?
4
Your result is 25 # Expected result
```
### Example of a function calling a function
```lang-py
def i_say_balls():
print('balls to you')
def say_balls():
i_say_balls()
say_balls() # remember to call the function!
```
_Note that I leave two empty lines below the defintion of each of my functions. This is a common practice in Python to keep things easy to read._
### Write your code here
```lang-py
```
Did that? You can now do anything with functions 🎉
## Exercise 4: Calculating Average
Write a function that returns `True` if the person enters **"hot dog"** or **"hotdog"**, or **"Hot Dog"**, otherwise `False`. The output of the program should be `Yes` or `No` depending on whether it's a hot dog.
### Examples of what the console interaction would look like
#### Example 1: With hot dog
```bash
Is Hot Dog?
hot dog
Yes # Expected result
```
### Paste your code here
```lang-py
def hotdog():
print ('What is your word?')
user_input = input()
if user_input == "hot dog" or "hotdog" or "Hot Dog":
return True
else:
return False
def yes_no():
if hotdog() == True:
return print('Yes')
else:
return print('No')
yes_no()
```
Bored already? Let's take it ☝️ a notch with (in the voice of a host of a wrestling match) COOOONDITIONAAALS!!
## Exercise 5: Add or Average?
Write a function that returns `True` if the person enters **"hot dog"** or **"hotdog"**, or **"Hot Dog"**, otherwise `False`. The output of the program should be `Yes` or `No` depending on whether it's a hot dog.
### Examples of what the console interaction would look like
#### Example 1: With hot dog
```bash
Is Hot Dog?
hot dog
Yes # Expected result
```
### Paste your code here
```lang-py
something = 13
```
I lied earlier 😉 Now you can really do anything with functions 🚀
## Exercise 6: What if I want to find the difference?
Write a function that returns `True` if the person enters **"hot dog"** or **"hotdog"**, or **"Hot Dog"**, otherwise `False`. The output of the program should be `Yes` or `No` depending on whether it's a hot dog.
### Examples of what the console interaction would look like
#### Example 1: With hot dog
```bash
Is Hot Dog?
hot dog
Yes # Expected result
```
### Paste your code here
```lang-py
something = 13
```
Almost there.. You got this ✊
## Exercise 7: Can I multiply?
Write a function that returns `True` if the person enters **"hot dog"** or **"hotdog"**, or **"Hot Dog"**, otherwise `False`. The output of the program should be `Yes` or `No` depending on whether it's a hot dog.
### Examples of what the console interaction would look like
#### Example 1: With hot dog
```bash
Is Hot Dog?
hot dog
Yes # Expected result
```
### Paste your code here
```lang-py
something = 13
```
Who's the most badass Python developer in the world??! You 👊
## Exercise 8: Divide & Conquer
Write a function that returns `True` if the person enters **"hot dog"** or **"hotdog"**, or **"Hot Dog"**, otherwise `False`. The output of the program should be `Yes` or `No` depending on whether it's a hot dog.
### Examples of what the console interaction would look like
#### Example 1: With hot dog
```bash
Is Hot Dog?
hot dog
Yes # Expected result
```
### Paste your code here
```lang-py
something = 13
```
🥇 Now let's put it all together
## Exercise 9: SimpleCalc
Write a function that returns `True` if the person enters **"hot dog"** or **"hotdog"**, or **"Hot Dog"**, otherwise `False`. The output of the program should be `Yes` or `No` depending on whether it's a hot dog.
### Examples of what the console interaction would look like
#### Example 1: With hot dog
```bash
Is Hot Dog?
hot dog
Yes # Expected result
```
### Paste your code here
```lang-py
something = 13
```
