These questions cover string indexing, concatenation, repetition, slicing, and justification.

For the following code...
```
x = 'I am a string'
y = 'me too'
print(x[2])
```
Predict what this code will do and answer Question 2 in your pre-lab.
For the following code...
```
x = 'I am a string'
y = 'me too'
print(x[2] + y[1])
```
Predict what this code will do and answer Question 3 in your pre-lab.
For the following code...
```
x = 'I am a string'
y = 'me too'
print(x + y)
```
Predict what this code will do and answer Question 4 in your pre-lab.
For the following code...
```
x = 'I am a string'
y = 'me too'
print(x + y)
print(x)
```
Predict what this code will do and answer Question 5 in your pre-lab.
For the following code...
```
x = 'I am a string'
y = 'me too'
print(2 * y)
```
Predict what this code will do and answer Question 6 in your pre-lab.
For the following code...
```
x = 'I am a string'
y = 'me too'
print(y[1:5])
```
Predict what this code will do and answer Question 7 in your pre-lab.
For the following code...
```
x = 'I am a string'
y = 'me too'
print(y[:5])
```
Predict what this code will do and answer Question 8 in your pre-lab.
For the following code...
```
x = 'I am a string'
y = 'me too'
print(y[1:])
```
Predict what this code will do and answer Question 9 in your pre-lab.
For the following code...
```
x = 'I am a string'
y = 'me too'
print(y[:])
```
Predict what this code will do and answer Question 10 in your pre-lab.

Part 2: String methods; lists of strings

For the following code...
```
x = 'I am a string'
print(x.upper())
```
Predict what this code will do and answer Question 11 in your pre-lab.
For the following code...
```
x = 'I am a string'
print(x.lower())
print(x)
```
Predict what this code will do and answer Questions 12 and 13 in your pre-lab.
For the following code...
```
x = 'I am a string'
z = x.split()
print(z[0])
print(x)
```
Predict what this code will do and answer Questions 14 and 15 in your pre-lab.
For the following code...
```
x = 'I am a string'
for w in x.split():
    print(w, end="")
print()
```
Predict what this code will do and answer Question 16 in your pre-lab.
For the following code...
```
x = 'I am a string'
y = x.split()
print(len(y))
```
Predict what this code will do and answer Question 17 in your pre-lab.

Part 3: Submit the pre-lab (due Tu at 7 AM)
