When it is required to find equidistant consecutive character strings, a list comprehension, the ‘all’ operator and the ‘ord’ method are used.
Example
Below is a demonstration of the same
my_list = ["abc", "egfg", "mpsv", "abed", 'xzbd', 'agms']
print("The list is :")
print(my_list)
my_result = [sub for sub in my_list if all(ord(sub[index + 1]) - ord(sub[index]) == ord(sub[1]) - ord(sub[0]) for index in range(0, len(sub) - 1))]
print("The resultant list is :")
print(my_result)Output
The list is : ['abc', 'egfg', 'mpsv', 'abed', 'xzbd', 'agms'] The resultant list is : ['abc', 'mpsv', 'agms']
Explanation
A list of string values is defined and is displayed on the console.
A list comprehension is used to iterate through the list.
The ‘all’ operator along with ‘ord’ method is used to check if the difference between next index and current index is equivalent to the first index and zeroth index.
This is assigned to a variable.
This is displayed as output on the console.
