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 printableFalse
- 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()
- returnsTrue
because'python programming'
is printable stringtext2.isprintable()
- returnsFalse
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
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.
