Ways to create a list of zeros in Python.
List are highly versatile and the process of creation of a list can be done in several ways, all of which will be thoroughly demonstrated in this tutorial.
Method 1:
- Create a list with one zero as its element.
- Repeat this list the required times using the
*operator.
# Create a list of zeros in Python list_zero = [0] #List with element 0 # Use the * operator to repeat this list list_new = list_zero * 10 print(list_new) # Output [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
In the above sample code, we use the * operator to create a list of zeros in Python.
Alternatively, the itertools can also be utilized to create a list of zeros in Python.
The repeat function from this library can create an iterator by repeating a given object a specified number of times.
Method 2:
- Use the
repeat()function to repeat the value. - Use the
list()function to convert the resultant object to a list.
# Create a list of zeros in Python # Use the repeat function list_new = list(itertools.repeat(0, 10)) print(list_new) # Output: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
The list function typecasts an object to a list.
The traditional approach of using a for loop can also be used to create a list of zeros in Python. This method uses the list comprehension technique where a for loop can create lists.
Method 3:
- Use the list comprehension technique to repeat zero in a list.
# Create a list of zeros in Python # Use the repeat function list_new = [0 for i in range(0, 10)] print(list_new) # Output: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
To conclude.
This particular article demonstrates several methods to create a list of zeros in Python. The main approach is to repeat this value in a list. This is achieved in the first method using the * operator. Next, we use the itertools.repeat() function to create a list of zeros. The last method shows the use of list comprehension to achieve the same.
