Definition
Python slice() function creates a slice of elements from a group of elements. Python slice() function return slice object, which represents the set of indices specified by range(start, stop, step).
In other words, a slice object is used to specify the start and endpoint of slicing.
Syntax
slice (start, stop, step).
Parameter Value
| Parameter | Type | Description |
|
start (optional) |
Integer |
|
| end (mandatory) | Integer | Specify the position to end slicing |
| step (optional) | Integer |
|
Return Value
Python slice() function returns slice object, which used to specify the sequence of slicing in the given indices.
Example of Python slice() List without step value
#Python program to illustrate the working of slicing function
#Using List (Without steps value)
my_List = [0,1,2,3,4,5,6,7,8,9]
#index 0,1,2,3,4,5,6,7,8,9
#index -10,-9,-8,-7,-6,-5,-4,-3,-2,-1
slicedValueObject = slice(0,5)
print(my_List[slicedValueObject])
Output
[0, 1, 2, 3, 4]
Example 2: Python slice() List with step value
#Python program to illustrate the working of slicing function
#Using List (With steps value)
my_List = [0,1,2,3,4,5,6,7,8,9]
#index 0,1,2,3,4,5,6,7,8,9
#index -10,-9,-8,-7,-6,-5,-4,-3,-2,-1
slicedValueObject = slice(0,5,2)
print(my_List[slicedValueObject])
OUTPUT:
[0, 2, 4]
Example 3: Python slice() with String without step value
#Python program to illustrate the working of slicing function
#Using String (without step value)
my_string = "You are on stechies.com"
#index 0,1,2,3,4,5,6,7,8,9
#index -10,-9,-8,-7,-6,-5,-4,-3,-2,-1
mySubString = slice(0,10);
print(my_string[mySubString])
OUTPUT:
You are on
Example 4: Python slice() with String with step value
#Python program to illustrate the working of slicing function
#Using String with alternate approach (with step value)
my_string = "You are on stechies.com"
#index 0,1,2,3,4,5,6,7,8,9
#index -10,-9,-8,-7,-6,-5,-4,-3,-2,-1
mySubString = slice(0,10,3);
print(my_string[mySubString])
OUTPUT:
Y en
Example 4: Python slice() with String with negative index
#Python program to illustrate the working of slicing function
#Using String with alternate approach (with negative index)
my_string = "You are on stechies.com"
#index 0,1,2,3,4,5,6,7,8,9
#index -10,-9,-8,-7,-6,-5,-4,-3,-2,-1
mySubString = slice(-15,-4);
print(my_string[mySubString])
OUTPUT
on stechies
