isprintable() : to check if all chars in a string are printable or not in Python

my_str.isprintable()

Returns True if all chars in a string are printable , otherwise rturns False

my_str='Welcome to plus2net'
print(my_str.isprintable())      # Output is False 

my_str='Welcome \t to plus2net'
print(my_str.isprintable())      # Output is False ( presence of Tab \t)

my_str='Welcome to plus2net \n'
print(my_str.isprintable())      # Output is False ( presence of line break \n)

my_str='1234'              
print(my_str.isprintable())      # Output is True

Handling Unicode Characters

Printable characters include Unicode characters, but control characters like tabs are non-printable:

my_str = 'Hello World 你好'
print(my_str.isprintable())  # True

Use Case: Sanitizing User Input

Check if user input contains only printable characters before processing:

user_input = 'ValidInput123!'
if user_input.isprintable():
    print("Input is valid.")

Output

Input is valid.

Checking Empty Strings

Empty strings are considered printable:

empty_str = ''
print(empty_str.isprintable())

True

Use Case: Validating Text for Output

Ensure text for a report contains only printable characters:

report_text = "Final Report: All data valid."
if report_text.isprintable():
    print("Ready for output.")

Ready for output.
