String Operations

String functions are used for manipulating and transforming text data in various ways. They can help you clean, format, and process textual data to make it more suitable for analysis or presentation.

Here are examples of using some string functions:

  • upper: Convert all characters in the string to uppercase.
  • lower: Convert all characters in the string to lowercase.
  • capitalize: Capitalize the first character of the string.
  • title: Capitalize the first character of each word in the string.
  • strip: Remove leading and trailing whitespace characters from the string.
  • lstrip: Remove leading whitespace characters from the string.
  • rstrip: Remove trailing whitespace characters from the string.
  • replace: Replace all occurrences of a substring with another substring.
  • substring: Extract a substring from the string by slicing.
  • reverse: Reverse the order of characters in the string.
  • removeprefix: Remove a specified prefix from the string
  • removesuffix: Remove a specified suffix from the string
  • split: Split the string into a list of substrings based on a specified delimiter.

These string functions are useful for processing and transforming text data, enabling you to clean, format, and analyze text more effectively.

Example

The "upper" operator is a string function that transforms all the characters in a given text string to uppercase. This operation is helpful when you need to standardize text data for comparison or analysis, as it ensures that case differences do not affect the results.

For example, the upper operator would transform the string "Machine Learning" into "MACHINE LEARNING".

In the context of data manipulation, you may want to apply the upper operator to a specific column in your dataset. Here's an example:

Dataset:

Name
Alice
Bob
Charlie

Apply the upper operator to the Name column:

Name
ALICE
BOB
CHARLIE
