Python String isprintable()

The isprintable() method returns True if all characters in the string are printable. If not, it returns False.


text = 'apple'

# returns True if text is printable result = text.isprintable()
print(result) # Output: True

isprintable() Syntax

The syntax of the isprintable() method is:


Here, isprintable() checks if string is printable or not.


  • Characters that occupy printing space on the screen are known as printable characters. For example letters and symbols, digits, punctuation, whitespace
  • Characters that do not occupy a space and are used for formatting is known as non-printable characters. For example line breaks, page breaks

isprintable() Parameters

The isprintable() method doesn't take any parameters.

isprintable() Return Value

The isprintable() method returns:

  • True - if all characters in the string are printable
  • False - if the string contains at least one non-printable character

Example 1: Python String isprintable()

text1 = 'python programming'

# checks if text1 is printable result1 = text1.isprintable()
print(result1) text2 = 'python programming\n'
# checks if text2 is printable result2 = text2.isprintable()



In the above example, we have used the isprintable() method to check whether the text1 and text2 strings are printable or not.


  • text1.isprintable() - returns True because 'python programming' is printable string
  • text2.isprintable() - returns False because 'python programming\n' contains a non-printable character '\n'

That means if we print text2, it does not print '\n' character,

# Output: python programing

Example 2: isprintable() with Empty String

The isprintable() method returns True when we pass an empty string. For example,

empty_string = ' '

# returns True with an empty string print(empty_string.isprintable())



Here, empty_string.isprintable() returns True.

Example 3: isprintable() with String Containing ASCII

# defining string using ASCII value 
text = chr(27) + chr(97)

# checks if text is printable if text.isprintable():
print('Printable') else: print('Not Printable')


Not Printable

In the above example, we have defined the text string using ASCII. Here,

  • chr(27) - is escape character i.e. backslash \
  • chr(97) - is letter 'a'

The text.isprintable() code returns False since chr(27) + chr(97) contains non printable escape character.

Hence the program executes the else part.
