When it is required to convert a string into a matrix that has ‘K’ characters per row, a method is defined that takes a string and a value for ‘K’. It uses a simple iteration, the modulus operator and the ‘append’ method.
Example
Below is a demonstration of the same −
print("Method definition begins") def convert_my_string(my_string, my_k): for index in range(len(my_string)): if index % my_k == 0: sub = my_string[index:index+my_k] my_list = [] for j in sub: my_list.append(j) print(' '.join(my_list)) print("Method definition ends") my_string = "PythonCode&Learn&ObjectOriented" print("The string is : " ) print(my_string) K = 3 print("The value of K is ") print(K) print("The result is :") print(convert_my_string(my_string, K))
Output
Method definition begins Method definition ends The string is : PythonCode&Learn&ObjectOriented The value of K is 3 The result is : P y t h o n C o d e & L e a r n & O b j e c t O r i e n t e d None
Explanation
A method is defined that takes a string and a K value as parameter, and returns as output.
Outside the method, a string is defined and is displayed on the console.
The value for K is defined and displayed in the console.
The method is called by passing the parameters.
This is displayed as output on the console.
