Python slice() FunctionPython slice() function is used to get a slice of elements from the collection of elements. Python provides two overloaded slice functions. The first function takes a single argument while the second function takes three arguments and returns a slice object. This slice object can be used to get a subsection of the collection. For example, if we want to get first two elements from the ten element?s list, here slice can be used. The signature of this function is given below. Signatureslice (stop) slice (start, stop[, step]) Parametersstart: Starting index of slicing. stop: End index of the slice step: The number of steps to jump. ReturnIt returns a slice object. Let's see some examples of slice() function to understand it's functionality. Python slice() Function Example 1# Python slice() function example # Calling function result = slice(5) # returns slice object result2 = slice(0,5,3) # returns slice object # Displaying result print(result) print(result2) Output: slice(None, 5, None) slice(0, 5, 3) Python slice() Function Example 2# Python slice() function example # Calling function str1 = "TheDeveloperBlog" slic = slice(0,10,3) # returns slice object slic2 = slice(-1,0,-3) # returns slice object # We can use this slice object to get elements str2 = str1[slic] str3 = str1[slic2] # returns elements in reverse order # Displaying result print(str2) print(str3) Output: Jaot toa Python slice() Function Example 3# Python slice() function example # Calling function tup = (45,68,955,1214,41,558,636,66) slic = slice(0,10,3) # returns slice object slic2 = slice(-1,0,-3) # returns slice object # We can use this slice object to get elements str2 = tup[slic] str3 = tup[slic2] # returns elements in reverse order # Displaying result print(str2) print(str3) Output: (45, 1214, 636) (66, 41, 68) Python slice() Function Example 4# Python slice() function example # Calling function tup = (45,68,955,1214,41,558,636,66) slic = slice(0,10,3) # returns slice object slic2 = tup[0:10:3] # fetch the same elements # We can use this slice object to get elements str2 = tup[slic] # Displaying result print(str2) print(slic2) Output: (45, 1214, 636) (45, 1214, 636)
