Spreadsheet systems like Microsoft Excel allow users to write macros using a rich inbuilt library of string and numerical functions, or to write arbitrary scripts using a variety of programming languages like Visual Basic, or .Net. Since end-users are not proficient in programming, they find it ...
The StringGrouper class The four functions mentioned above all create aStringGrouperobject behind the scenes and call different functions on it. TheStringGrouperclass keeps track of all tuples of similar strings and creates the groups out of these. Since matches are often not perfect, a common ...
Python Code: # Define a function named 'reverse' that takes an iterable 'itr' as input and returns its reversedefreverse(itr):# Using slicing with [::-1] reverses the input 'itr' and returns the reversed versionreturnitr[::-1]# Initialize a string variable 'str1' with the value '123...
Python provides many built-in methods or helper functions to manipulate strings. Replacing a substring, capitalizing certain words in a paragraph, finding the position of a string within another string are some of the operations you can do with these built-in methods. Take a look at some of ...
