1st week of Python

Learning the basics

Operation with other types

I struggled with this example. The instructions got me confused. I have listed them below.

Calculate the product of savings and growth_multiplier. Store the result in year1.

To me I thought to put the code below for this one so I got this right.
```
growth_multipler * savings = year1
```
What do you think the resulting type will be? Find out by printing out the type of year1.
I had no idea what to do here because we never talked about this type formula. How was I supposed to figure this out. I think I will try to use stack overflow next time.

Calculate the sum of desc and desc and store the result in a new variable doubledesc.

This was pretty easy

Print out doubledesc. Did you expect this?

I forgot how to print. Now I know it is like below.
```
print()
```

This is the solution below

```savings = 100 growth_multiplier = 1.1 desc = “compound interest”

Assign product of savings and growth_multiplier to year1

year1 = savings * growth_multiplier

Print the type of year1

print(type(year1))

Assign sum of desc and desc to doubledesc

doubledesc = desc + desc

Print out doubledesc

print(doubledesc)

Type Conversion 
- Using + operator to paste together 2 strings can be very useful 

All of these can be used to do type conversion.
str() 
float()
int()

I didnt understand how to type convert in the problem they game me. 
- I am still working on the problem. 

v# Definition of savings and result savings = 100 result = 100 * 1.10 ** 7

Fix the printout

print(“I started with $” + str(savings) + “ and now have $” + str(result) + “. Awesome!”)

Definition of pi_string

pi_string = “3.1415926”

Convert pi_string into float: pi_float

pi_float = float(pi_string)

I got it right!  I used the hint because I did not understand how to create this at first glance. 
- Use float() on pi_string and store the result in pi_float.

I ended up prining out with the code above and it worked!

In [11]: I started with $100 and now have $194.87171000000012. Awesome!

output: I started with $100 and now have $194.87171000000012. Awesome! ```
