Introduction to Python Test Empty String
Python was developed by Guido van Rossum between 1985 and 1990, and it is a high-level, object-oriented, interactive, general-purpose computer language. Python, like Perl, is released under the GNU general public licence. Python’s strings are immutable, and the language’s operation handling is difficult. Remember that a string with spaces is not zero length because the size of a string with spaces is not zero. Testing an empty string in Python is covered here. In this article, we will discuss methods for determining whether or not a given string is empty or contains characters.
characters.
Syntax of Python Test Empty String
If you want to know whether a String in Python is empty, you may use one of many different syntaxes:
-
Using ‘len()’ Method
len(Stringy_string) == 0
-
Using ‘not’ Method
not Stringy_string
-
Using ‘not + str.strip()’ Method
not (Stringy_string and Stringy_string.strip())
-
Using ‘not + str.isspace’ Method
not (Stringy_string and not Stringy_string.isspace())
Examples of Python Test Empty String
Here are some examples of how to use Python to check whether a string is empty.
These are several instances of checking to see whether a string is empty. “Nothing Found, hence it is EMPTY” is displayed if the string is empty. The code prints “Something Discovered, thus it is NOT EMPTY” if the string is not empty.
execution.
1. Method 1 – Using ‘len()’
The most well-known approach to determining whether a string has zero characters. Unfortunately, it does not take into account the fact that a string consisting only of spaces should be treated as an empty string despite not having a value of zero. As an initial case in point, the code:
Produced Stringy_string = ""
print ("Is the string contains anything or it is Empty? \n"
, end = "")
if(len(Stringy_string) == 0):
print ("\nNothing Found, so it is EMPTY")
else :
print ("Something Found, so it is NOT EMPTY")
print ("\nLet's move to next example now, which have something in it. \n")
:
Code 2: W01A9@@@
Output
Stringy_string = "I have something"
print ("Is the string contains anything or it is Empty? \n"
, end = "")
if(len(Stringy_string) == 0):
print ("\nNothing Found, so it is EMPTY")
else :
print ("Something Found, so it is NOT EMPTY")
print ("\nLet's move to next method now, with different examples. \n")
:
2. Method 2 – Using ‘not’
The not operator, like len(), may be used to find strings that have no value. Incorrectly, it also ignores strings consisting entirely of spaces. First Instance Code:
Its Output is Stringy_string = "",
print ("Is the string contains anything or it is Empty? \n"
, end = "")
if(not Stringy_string):
print ("\nNothing Found, so it is EMPTY")
else :
print ("Something Found, so it is NOT EMPTY")
print ("\nLet's move to next example now, which have something in it. \n")
The Second Instance of the 
Code:
Its Output is Stringy_string = "I have something"
print ("Is the string contains anything or it is Empty? \n"
, end = "")
if(not Stringy_string):
print ("\nNothing Found, so it is EMPTY")
else :
print ("\nSomething Found, so it is NOT EMPTY")
print ("\nLet's move to next method now, with different examples. \n")
Instance 1 of the
3. Method 3 – Using ‘not + str.strip()’
Code:
As a result of Stringy_string = ""
print ("Is the string contains anything or it is Empty? \n"
, end = "")
if(not (Stringy_string and Stringy_string.strip())):
print ("\nNothing Found, so it is EMPTY")
else :
print ("Something Found, so it is NOT EMPTY")
print ("\nLet's move to next example now, which have something in it. \n")
Processing:
Code 2: 
Resulting Stringy_string = "I have something"
print ("Is the string contains anything or it is Empty? \n"
, end = "")
if(not (Stringy_string and Stringy_string.strip())):
print ("\nNothing Found, so it is EMPTY")
else :
print ("\nSomething Found, so it is NOT EMPTY")
print ("\nLet's move to next method now, with different examples. \n")

4. Method 4 – Using ‘not + str.isspace’
Code:
Resulting Stringy_string = ""
print ("Is the string contains anything or it is Empty? \n"
, end = "")
if(not (Stringy_string and not Stringy_string.isspace())):
print ("\nNothing Found, so it is EMPTY")
else :
print ("Something Found, so it is NOT EMPTY")
print ("\nLet's move to next example now, which have something in it. \n")
Second Instance Code: 
The Results of the Stringy_string = "I have something"
print ("Is the string contains anything or it is Empty? \n"
, end = "")
if(not (Stringy_string and not Stringy_string.isspace())):
print ("\nNothing Found, so it is EMPTY")
else :
print ("\nSomething Found, so it is NOT EMPTY")
print ("\nLet's move to next method now, with different examples. \n")
