# Python: Split values into two groups, based on the result of the given filter list

## Python List: Exercise - 231 with Solution

Write a Python program to split values into two groups, based on the result of the given filter list.

• Use a list comprehension and zip() to add elements to groups, based on filter.
• If filter has a truthy value for any element, add it to the first group, otherwise add it to the second group.

Sample Solution:

Python Code:

``````def bifurcate(colors, filter):
return [
[x for x, flag in zip(colors, filter) if flag],
[x for x, flag in zip(colors, filter) if not flag]
]
print(bifurcate(['red', 'green', 'blue', 'pink'], [True, True, False, True]))
```
```

Sample Output:

```[['red', 'green', 'pink'], ['blue']]
```

## Python: Tips of the Day

Decapitalizes the first letter of a string:

Example:

```def tips_decapitalize(s, upper_rest=False):
return s[:1].lower() + (s[1:].upper() if upper_rest else s[1:])
print(tips_decapitalize('PythonTips'))
print(tips_decapitalize('PythonTips', True))
```

Output:

```pythonTips
pYTHONTIPS
```
