# Control Flow

#### Conditional Statements

**if**

```python
name = 'Arthur'
if name == 'Arthur':
    print("I didn't know we 'ad a king!")
```

*NOTE*

* Indentation creates a block
* A colon, `:`, is required at the beginning of a block
* Use 4 spaces per indentation level (from the [official style guide](https://peps.python.org/pep-0008/#indentation))

**elif**

```python
name = 'Galahad
if name == 'Arthur':
    print("I didn't know we 'ad a king!")
elif name == 'Galahad':
    print("Sir Galahad! You would not be so ungallant as to refuse our hospitality.")
```

**else**

```python
name = 'Galahad
if name == 'Arthur':
    print("I didn't know we 'ad a king!")
elif name == 'Galahad':
    print("Sir Galahad! You would not be so ungallant as to refuse our hospitality.")
else:
    print("Who are you?")
```

#### Loops

**while loop**

```python
i = 0
while i < 11:
    print('Loop #', i)
    i += 1
```

**for loop**

```python
for char in 'spam':
    print(char)
```

**range** `range(start, stop, step)`

The `range` function returns a sequence of numbers that starts from `start` (0 by default) and stops before `stop`, in increments of `step` (1 by default).

```python
for i in range(11):
    print('Loop #', i)
```

```python
for i in range(1, 11):
    print('Loop #', i)
```

```python
for i in range(10, 101, 10):
    print('Loop #', i)
```

**break & continue** You can stop a loop with `break` or skip to the next iteration with `continue`

```python
for i in range(100):
    if i % 2 != 0:
        print('odd number')
        continue
    elif i == 42:
        print('Stop at 42')
        break
    else:
        print(i)
```
