# Strings

* ' ' and " " are the same
* `chr(ord('a')+1)` to add one to 'a' and get 'b'
* Python 3 has strings be unicode, 2 byte character

```python
" ".join(["jorge", "sucks"]) #=> "jorge sucks"
"hi".upper() #"HI"
"Hi".lower() #"hi"

txt = "Enjoy life!"
new_txt = txt.replace("life", "everything")
```

## Formatting

Python 3 handles {} others need {0}

```python
`"Hi {} there {}".format(firstP, secondP)`
'{:02d}'.format(i) #print with 2 places

"My quest is {name}".format(name="jorge")             # References keyword argument 'name'

# 3.6
f"Hello, {name}. You are {age}."
```

* Returns a single string with {} replaced

## r"..." = raw

still string, but treats backslashes as literals instead of escape characters

### u"...." = Unicode

## Check proper

```python
'a'.isalpha()
'1'.isdigit()
```

## Get lists

```
string.ascii_uppercase
```

### Other

```python
x.startswith("Start")
```
