Python String isprintable()

In this tutorial, you will learn about the Python String isprintable() method with the help of examples.

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

Example

text = 'apple'

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

print(result)

# Output: True

isprintable() Syntax

The syntax of the isprintable() method is:

string.isprintable()

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

Note:

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() 
print(result2)

Output

True
False

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

Here,

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,

print(text2)
# 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())

Output

True

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')

Output
