The Python String isprintable() method is a built-in function that returns true if all the characters in a string are printable or if the string is empty. If not, it returns False.
What are printable characters in Python?
In Python, the character that occupies printing space on the screen is known as a printable character.
Examples of Printable characters are as follows –
- symbols and punctuation
The Syntax of
isprintable() method is:
isprintable() method does not take any parameters.
isprintable() method returns
Trueif the string is empty or all the character in the string is printable
Falseif the string contains at least one non-printable character
Example 1: Working of isprintable() method
# valid text and printable text = 'These are printable characters' print(text) print(text.isprintable()) # \n is not printable text = '\nNew Line is printable' print(text) print(text.isprintable()) # \t is non printable text = '\t tab is printable' print(text) print(text.isprintable()) # empty character is printable text = '' print('\nEmpty string printable?', text.isprintable())
These are printable characters True New Line is printable False tab is printable False Empty string printable? True
Example 2: How to use isprintable() in the actual program
In the below Program, we will iterate the given text to check and count how many non-printable characters are there. If we find any non-printable characters we will be replacing it with empty characters and finally, we will output the printable characters into ‘newtext’
text = 'Welcome to ItsMyCode,\nPython\tProgramming\n' newtext = '' # Initialising the counter to 0 count = 0 # Iterate the text, count the non-printable characters # replace non printable characters with empty string for c in text: if (c.isprintable()) == False: count += 1 newtext += ' ' else: newtext += c print("Total Non Printable characters count is:", count) print(newtext)
Total Non Printable characters count is: 3 Welcome to ItsMyCode, Python Programming
