Python: Check common elements between two given list are in same order or not
Python List: Exercise - 133 with Solution
Write a Python program to check common elements between two given list are in same order or not.
Sample Solution:
Python Code:
def same_order(l1, l2):
common_elements = set(l1) & set(l2)
l1 = [e for e in l1 if e in common_elements]
l2 = [e for e in l2 if e in common_elements]
return l1 == l2
color1 = ["red","green","black","orange"]
color2 = ["red","pink","green","white","black"]
color3 = ["white","orange","pink","black"]
print("Original lists:")
print(color1)
print(color2)
print(color3)
print("\nTest common elements between color1 and color2 are in same order?")
print(same_order(color1, color2))
print("\nTest common elements between color1 and color3 are in same order?")
print(same_order(color1, color3))
print("\nTest common elements between color2 and color3 are in same order?")
print(same_order(color2, color3))
Sample Output:
Original lists: ['red', 'green', 'black', 'orange'] ['red', 'pink', 'green', 'white', 'black'] ['white', 'orange', 'pink', 'black'] Test common elements between color1 and color2 are in same order? True Test common elements between color1 and color3 are in same order? False Test common elements between color2 and color3 are in same order? False

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")
