The above code is amended to look like this: if len(some_string.strip()) = 0: If you think that there may be leading or trailing whitespace characters in blank strings, you can use the strip() method before checking its length. This code checks for a zero-length string: if len(some_string) = 0: If the length is zero, the string is empty. The len() function returns the length of Python strings. This code snippet illustrates how: if str1 = '': You can compare a string variable with a quoted empty string using the eq operator to check for equality.
