String isspace() Method Examples in Python

Method #1: Using Built-in Functions (Static Input)

Approach:

  • Give the string as static input and store it in a variable.
  • Apply isspace() function to the given string in which if the string contains only whitespace characters, the isspace() method returns True. If it does not, it returns False.
  • Store it in another variable.
  • Print the above-given String.
  • Print the result after checking if the given string has only whitespace characters or not.
  • Similarly, do the same for other strings and print the result.
  • The Exit of Program.

Below is the implementation:

# Give the string as static input and store it in a variable.
gvn_strng1 = '  Python-programs  '
# Apply isspace() function to the given string in which if the string
# contains only whitespace characters, the isspace() method returns True.
# If it does not, it returns False.
# Store it in another variable.
rslt_1 = gvn_strng1.isspace()
# Print the above-given String.
print("The given string = ", gvn_strng1)
# Print the result after checking if the given string has only whitespace
# characters or not.
print("Checking if the given string is has whitespace or not = ", rslt_1)
# Similarly, do the same for other strings and print the result.
gvn_strng2 = '    \t'
rslt_2 = gvn_strng2.isspace()
print("The given string = ", gvn_strng2)
print("Checking if the given string is whitespace or not = ", rslt_2)

gvn_strng3 = ''
rslt_3 = gvn_strng3.isspace()
print("The given string = ", gvn_strng3)
print("Checking if the given string is whitespace or not = ", rslt_3)

Output:

The given string =    Python-programs  
Checking if the given string is has whitespace or not =  False

Python memoryview() Function with Examples

Python / By

In the previous article, we have discussed Python Program for ord() Function
The memoryview() function in Python returns memory views objects. Before delving deeper into the memoryview() function, consider why we use it.

Why are we using the memoryview() function?
Because Memory view is a safe way to expose the buffer protocol in Python and a memoryview behaves like bytes in many useful contexts (for example, it supports the mapping protocol), it can serve as an adequate replacement if used correctly. The best part is that it uses the buffer protocol under the hood to avoid copies and simply juggle pointers to data. So, before we get into what memory views are available, we must first understand the Buffer Protocol.

What is buffer protocol?

The buffer protocol allows you to access an object’s internal data. This internal data is in the form of a memory array or a buffer. It enables one object to expose its internal data (buffers) and another to access those buffers without requiring intermediate copying. The buffer protocol is only available to us at the C-API level, not through our normal codebase. Memory views are used to expose the same protocol to a standard Python codebase.

Memoryview

Memoryview objects enable Python code to access the internal data of an object that supports the buffer protocol without the need for copying. The memoryview() function provides direct read and write access to byte-oriented data in an object without the need to copy it first. Because it does not create a copy when slicing, this can result in significant performance gains when working with large objects.

Syntax:

memoryview(object)

Parameters

object: The object whose internal data will be exposed.
buffer protocol support – str and bytearray (but not Unicode).

Return Value:

A memoryview object is returned.

Examples:

Example1:

Input:

Given String = 'EFG'

Output:

69
b'EFG'
[69, 70, 71]

Example2:

Input:

Given String = 'uvw'

Output:

117
b'uvw'
[117, 118, 119]

Program for memoryview() Function in Python

Method #1: Using Built-in Functions (Static Input)

Approach:

  • Take a random string and pass it to the bytearray() function with the second argument as ‘utf-8’ and store it in a variable.
  • Calculate the memoryview of the above bytearray by passing the above bytearray to memoryview () function.
  • Store it in another variable.
  • Print or access the zeroth index of the memoryview using the memoryview[0].
  • Create the byte from the memoryview by passing memoryview with slicing to bytes() function and print it.
  • Create a list from the memoryview by passing the memoryview with slicing and convert it into list using the list() function and print it.
  • The Exit of the Program.

Below is the implementation:

# Take a random string and pass it to the bytearray() function with the
# second argument as 'utf-8' and store it in a variable.
randmbyte_arry = bytearray('EFG', 'utf-8')
# Calculate the memoryview of the above bytearray by passing the above
# bytearray to memoryview () function.
# store it in another variable.
memryvieww = memoryview(randmbyte_arry)
# Print or access the zeroth index of the memoryview using the memoryview[0].
print(memryvieww[0])
# Create the byte from the memoryview by passing memoryview with slicing to
# bytes() function and print it.
print(bytes(memryvieww[0:3]))
# Create a list from the memoryview by passing the memoryview with slicing
# and convert it into list using the list() function and print it.
print(list(memryvieww[0:5]))

Output:

69
b'EFG'
[69, 70, 71]

gvn_str = input("Enter some random string = ")
# Take the above random string and pass it to the bytearray() function with the
# second argument as 'utf-8' and store it in a variable.
randmbyte_arry = bytearray(gvn_str, 'utf-8')
# Calculate the memoryview of the above bytearray by passing the above
# bytearray to memoryview () function.
# store it in another variable.
memryvieww = memoryview(randmbyte_arry)
# Print or access the zeroth index of the memoryview using the memoryview[0].

Python Program to Find Index of a Tuple Item

Python / By

In the previous article, we have discussed Python Program for memoryview() Function
The tuple index function in Python returns the index of a given tuple item. The index position of the first found value is returned by the tuple index function.

Syntax:

TupleName.index(tupleValue, start, end)

If you specify a start value, the index function will begin searching from that point. Similarly, setting the end position causes the tuple index function to stop looking at that number.

Examples:

Example1:

Input:

Given tuple = (10, 20, 30, 50, 70, 20)
Given first number = 50
Given second number = 20
Given start position = 2

Output:

The given number's 50 index position =  3
The given number's 20 index position after the given start position 2 =  5

Example2:

Input:

Given tuple = (1, 3, 5, 7, 8, 2, 5)
Given first number = 3
Given second number = 5
Given start position = 3

Output:

The given number's 3 index position =  1
The given number's 5 index position after the given start position 3 =  6
