When it is required to convert a matrix into a string, a simple list comprehension along with the ‘join’ method can be used.
Example
Below is a demonstration of the same
my_list = [[1, 23, "python"], [1, "is", 24], ["fun", 97, 5]]
print("The list is :")
print(my_list)
in_delete, out_delete = ",", " "
my_result = out_delete.join([in_delete.join([str(element) for element in sub]) for sub in my_list])
print("The output string is :")
print(my_result)Output
The list is : [[1, 23, 'python'], [1, 'is', 24], ['fun', 97, 5]] The output string is : 1,23,python 1,is,24 fun,97,5
Explanation
A list of list is defined and is displayed on the console.
Two variables with symbols are defined.
A list comprehension is used to iterate through the elements in the list.
The elements are joined based on a specific condition.
This is assigned to a variable.
This variable is displayed as output on the console.
