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')]

Previous: Write a Python program to remove additional spaces in a given list.
Next: Sum a list of numbers. Write a Python program to sum the first number with the second and divide it by 2, then sum the second with the third and divide by 2, and so on.

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
