## Using Range

Print the even numbers from 1 to 10

```
numbers = range(1, 11)
for number in numbers:
if number % 2 == 0:
print number
```

## Simpler

```
for number in range(1, 11):
if number % 2 == 0:
print number
```

####Or for number in range(2, 11, 2): print number

## Using Range to Loop Over Values in a List

In many languages we can use for value in values so we use the indexes to loop over values in a list

```
sequences = ['atg', 'gtc', 'atta']
for i in range(len(sequences)):
print sequences[i]
```

And we can use this in Python to loop over two lists simultaneously

```
seqID = [27, 63, 42]
sequences = ['atg', 'gtc', 'atta']
for i in range(len(sequences)):
print seqID[i], sequences[i]
```

## Enumerate

Alternatively we can use enumerate

```
seqID = [27, 63, 42]
sequences = ['atg', 'gtc', 'atta']
for i, sequence in enumerate(sequences):
print seqID[i], sequence
```
