# Python: Common tuples between two given lists

## Python List: Exercise - 207 with Solution

Write a Python program to find the common tuples between two given lists.

Sample Solution:

Python Code:

``````def test(list1, list2):
result =  set(list1).intersection(list2)
return list(result)
list1 =  [('red', 'green'), ('black', 'white'), ('orange', 'pink')]
list2 =  [('red', 'green'), ('orange', 'pink')]
print("\nOriginal lists:")
print(list1)
print(list2)
print("\nCommon tuples between two said lists")
print(test(list1,list2))
list1 =  [('red', 'green'), ('orange', 'pink')]
list2 =  [('red', 'green'), ('black', 'white'), ('orange', 'pink')]
print("\nOriginal lists:")
print(list1)
print(list2)
print("\nCommon tuples between two said lists")
print(test(list1,list2))
```
```

Sample Output:

```Original lists:
[('red', 'green'), ('black', 'white'), ('orange', 'pink')]
[('red', 'green'), ('orange', 'pink')]

Common tuples between two said lists
[('orange', 'pink'), ('red', 'green')]

Original lists:
[('red', 'green'), ('orange', 'pink')]
[('red', 'green'), ('black', 'white'), ('orange', 'pink')]

Common tuples between two said lists
[('orange', 'pink'), ('red', 'green')]
```

## Python: Tips of the Day

Returns True if the provided function returns True for every element in the list, False otherwise:

Example:

```def tips_every(lst, fn=lambda x: x):
return all(map(fn, lst))

print(tips_every([2, 4, 3], lambda x: x > 1))
print(tips_every([1, 2, 3]))
```

Output:

```True
True
```
