Program Code – Python Like Statement: SQL-Like Operations in Python


import pandas as pd

# Simulate a database table using a DataFrame.
data = pd.DataFrame({
    'user_id': [1, 2, 3, 4, 5],
    'name': ['Alice', 'Bob', 'Charlie', 'David', 'Eva'],
    'country': ['USA', 'USA', 'UK', 'UK', 'UK'],
})

# Define the 'like' operation (similar to SQL's LIKE).
def like_operation(df, column, pattern):
    # Handle the pattern by replacing % with reg-ex equivalent .* 
    # and escape other reg-ex special characters
    regex_pattern = pattern.replace('%', '.*').replace('.', '\.')
    return df[df[column].str.match(regex_pattern)]

# Example Usage: Find names that start with 'A' and end with 'e'.
result = like_operation(data, 'name', 'A%e')

print(result)

Code Output:

   user_id   name country
0        1  Alice     USA

Code Explanation:

The generated program is designed to mimic the SQL ‘LIKE’ operation in Python using the powerful pandas library. Here’s a walkthrough of the code’s logic and architecture:

  1. Import the pandas library: Necessary for creating data structures similar to database tables and manipulating them.
  2. Create DataFrame ‘data’: This step simulates a database table with columns ‘user_id’, ‘name’, and ‘country’. We fill it with some example data that the ‘LIKE’ operation will later filter.
  3. Define the function ‘like_operation()’: This function takes three arguments: a pandas DataFrame ‘df’, a column name ‘column’ in which to perform the operation, and the ‘pattern’ to use for matching.
  4. Handle RegEx Pattern: In the function, SQL ‘LIKE’ operator’s ‘%’ sign is replaced with the regular expression ‘.*’, allowing any number of characters to be in place. We also escape any other special Regex characters in the pattern to ensure correct pattern matching.
  5. Perform the ‘like’ Operation: The function filters the DataFrame using the str.match() method, which matches the regex pattern against the specified ‘column’ of the DataFrame.
  6. Example Usage: We call the ‘like_operation()’ function, looking for names in the ‘name’ column that start with ‘A’ and end with ‘e’ using the pattern ‘A%e’.
  7. Print result: The output is printed to the console, and as expected, it returns the row corresponding to the name ‘Alice’, which satisfies the condition.

The code achieves its objective by closely simulating the behavior of the SQL ‘LIKE’ operation in a non-database environment, utilizing Python’s built-in capabilities and pandas DataFrame functionality, showing the flexibility of Python to handle database-like operations.
