Exercise: Format some string information to look like so:
John Doe
123 Main Street
AnyCity, AS 09876

```first='John'
last= 'Doe'
street='Main Street'
number= 123
city = 'AnyCity'
state='AS'
zipcode='09876'

print('{0} {1}\n{2} {3}\n{4}, {5} {6}'.format(first,last,number, street, city, state, zip code))
```

Exercise: Write a function that will take a list of data (last, first, class, average grade) and output formatted text in columns.

My Solution: I did a bit of trial and error in the IDE to get the text to line up correctly.

```students = []
def roster(*x):
for i in students:
print('{0:20}{1:20}{2:20}{3:20}'.format(i,i,i,i))
```

When a user adds to the list like so:

```students.append(['DeMoines','Jim','Sophmore','3.45'])
students.append(['Backer','Bill','Junior','2.45'])
students.append(['Hill','Jack','Freshman','4.00'])
students.append(['Mary','Mary','Sophmore','3.23'])
```

This will return the following output:

```Last                First               Class               Average Grade
DeMoines            Jim                 Sophmore            3.45
Backer              Bill                Junior              2.45
Hill                Jack                Freshman            4.00
Mary                Mary                Sophmore            3.23
```

Exercise: Make a function that takes a multi word string and turns it into an acronym.

My Solution: I decided to split the words in a sentence on the space between each word. This puts the words into list (x_list.) Then I loop over the elements in the list and add the first letter of each word in the x_list, into a new list called ac (upper casing the letters as well.) Finally I turn the ac list into a string, which is output.

```def acronym(x):
x_list = x.split(" ")
ac = []
for y in x_list:
ac.append(y.upper())
print(''.join(ac))

acronym("This is a test")
```

The join syntax still bugs me. It seems more logical to write: ac.join(”) rather then ”.join(ac)
