Python program to find all the Combinations in the list with the given condition

When it is required to find all the combinations in the list with the given condition, a simple iteration, the append method, and the ‘isinstance’ method are used.

Example

Below is a demonstration of the same −

my_list = ["python", [15, 12, 33, 14], "is", ["fun", "easy", "better", "cool"]]

print("The list is :")
print(my_list)

K = 4
print("The value of K is :")
print(K)

my_result = []
count = 0
while count <= K - 1:
   temp = []

   for index in my_list:

      if not isinstance(index, list):
         temp.append(index)
      else:
         temp.append(index[count])
   count += 1
   my_result.append(temp)

print("The result is :")
print(my_result)

Output

The list is :
['python', [15, 12, 33, 14], 'is', ['fun', 'easy', 'better', 'cool']]
The value of K is :
4
The result is :
[['python', 15, 'is', 'fun'], ['python', 12, 'is', 'easy'], ['python', 33, 'is', 'better'], ['python', 14, 'is',
'cool']]

Explanation

• A list of integers is defined and is displayed on the console.

• A value for K is defined and is displayed on the console.

• An empty list is created.

• A variable ‘count’ is created and is assigned to 0.

• A while loop is used to iterate over the list, and the ‘isinstance’ method is used to check if the type of element matches a specific type.

• Depending on this, the element is appended to the empty list.

• This is the output that is displayed on the console.
