Python ascii() Method with Examples

Python / By

In the previous article, we have discussed Python Program for all() Function
ascii() Function in Python:

The ascii() function returns an object’s readable version (Strings, Tuples, Lists, etc).

Any non-ascii characters will be replaced with escape characters by the ascii() function.

It uses the \x, \u, or \U escapes to escape non-ASCII characters in the string.

For Example:

ö has been replaced with \xf6n.

Ã¥ has been replaced with \xe5.

Syntax:

ascii(object)

Parameters

object: An object, such as a String, List, Tuple, Dictionary, and so on.

Return Value:

It returns a string containing an object’s printable representation.

For instance, ö is changed to \xf6n and √ is changed to \u221a.

The string’s non-ASCII characters are escaped with \x, \u, or \U.

Examples:

Example1:

Input:

Given first string = "welcome to Pythön-Prögrams"
Given second string = "hello this is btechgeeks"

Output:

The given first string after applying ascii() function =  'welcome to Pyth\xf6n-Pr\xf6grams'
The given second string after applying ascii() function =  'hello this is btechgeeks'

Example2:

Input:

Given first string =  "gööd morning all"
Given second string = "hello this is vikråm chiluka"

bool() Function in Python:

Using the standard truth testing procedure, the Python bool() function returns or converts a value to a Boolean value, i.e., True or False.

Syntax:

bool([value])

Parameters

In general, the bool() method takes only one parameter (value), to which the standard truth testing procedure can be applied. If no parameters are passed, it returns False by default. As a result, passing a parameter is optional.

Return Value:

bool() function can only return one of two values.

  • If the parameter or value passed is True, it returns True.
  • If the parameter or value passed is False, it returns False.

Here are some examples of when Python’s bool() method returns false. Except for these, all other values are True.

  1. If the value False is passed.
  2. If the value None is used.
  3. If an empty sequence, such as (), [], “, etc., is passed
  4. If any numeric type, such as 0, 0.0, etc., is passed as Zero,
  5. If an empty mapping, such as, is passed.
  6. Objects of Classes with __bool__() or __len()__ methods that return 0 or False

Python bytes() Function with Examples

Python / By

In the previous article, we have discussed Python Program for bool() Function
bytes() Function in Python:

The bytes() function returns an object of type bytes.

The bytes() method returns a bytes object, which is an immutable (cannot be changed) sequence of integers ranging from 0 to 256.

It can either convert objects to bytes objects or create an empty bytes object of the specified size.

The distinction between bytes() and bytearray() is that bytes() return an object that cannot be modified, whereas bytearray() returns a modifiable object.

Syntax:

bytes(x, encoding, error)

Parameters

x: When creating the bytes object, this is the source that will be used.

If it is an integer, it will generate an empty bytes object of the specified size.

If it’s a String, make sure to specify the source’s encoding.

encoding(optional): The string’s encoding.

error(optional): Specifies what should happen if the encoding fails.

Return Value:

The bytes() method returns bytes object with the specified size and initialization parameters.

Examples:

Example1:

Input:

Given number = 6

Output:

The result after applying the bytes() method to the given number 6 = b'\x00\x00\x00\x00\x00\x00'

Example2:

Input:

Given string =  "welcome to Python-programs"

Output:

The result after applying the bytes() method to the given string = b'welcome to Python-programs'

Python compile() Function with Examples

Python / By

In the previous article, we have discussed Python Program for bytes() Function
compile() Function in Python:

The compile() function returns the specified source as a ready-to-execute code object.

Syntax:

compile(source, filename, mode, flag, dont_inherit, optimize)

Parameters:

source: This is Required. A String, a Bytes object, or an AST object can be used as the source to compile.

filename: Required. The name of the file from which the source was obtained. If the source is not a file, you can type whatever you want.

mode: This is Required. Legal principles:

  • If the source is a single expression, use eval.
  • If the source is a set of statements, use exec.
  • If the source is a single interactive statement, use single

flag: This is Optional. The process of compiling the source code. 0 is the default.

dont_inherit: This is Optional. The process of compiling the source code. False by default

optimize: This is Optional. Defines the compiler’s optimization level. -1 is the default.

Return value:

Python code object is returned by the compile() function.

Examples:

Example1:

Input:

Given code in string = 'p = 4\nq=7\nmult=p*q\nprint("The multiplication result =",mult)'

Output:

The multiplication result = 28

Example2:

Input:

Given code in string = 'p = 25\nq=5\ndivisn=p/q\nprint("The division result =",divisn)'

Output:

The division result = 5.0

Program for compile() Function in Python

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

Approach:

  • Give the Python code as a string that multiplies the given two numbers and store it in a variable.
  • Compile the given code using the compile() function with the parameters as the above string code, codename, and mode of compilation.
  • Print the above result which is the code after compilation.
  • The Exit of the Program.

Below is the implementation:

# Give the Python code as a string that multiplies the given two numbers
# and store it in a variable.
codeIn_gvnstring = 'p = 4\nq=7\nmult=p*q\nprint("The multiplication result =",mult)'
# Compile the given code using the compile() function with the parameters
# as the above string code, codename, and mode of compilation.
code_obejct = compile(codeIn_gvnstring, 'multstring', 'exec')
# Print the above result which is the code after compilation.
exec(code_obejct)

Output:

The multiplication result = 28

Explanation:

In this case, the source is a regular string. multstring is the filename. Furthermore, the exec mode later allows the use of the exec() method.

The compile() method transforms a string into a Python code object. The exec() method is then used to execute the code object.
