# Function to_JSON_format( ), the function takes a CSV formatted string and returns the corresponding JSON format string. Use String Methods find() ,string slicing and string concatenation to implement the required functionality.
# Create a main function as shown in the in-class lab section. Add function calls to get the book information, produce and display the csv

To convert a CSV string to JSON format in Python, you can use the built-in csv and json modules. Here is an example code that demonstrates how to do this:
import csv
import json
csv_string = """name,age,cit y
John,25,New York
Alice,30,Los Angeles
Bob,35,Chicago" ""

# Read the CSV string into a list of dictionaries
csv_data = []
reader = csv.DictReader( csv_string.spli tlines())
for row in reader:
csv_data.append (row)

# Convert the CSV data to JSON format
json_data = json.dumps(csv_ data)
print(json_data )

Dear Friends, Python assignment is a reference assignment. However, I really can't explain the difference in the following example. When the object is a list, the assignment seems to be a reference. However, when the object is a number, the story is so different. I don't understantd for what reason Python deals with them differently. The example is as follows: >>> a = >>> b = a

Hi all. I would like to ask how I can implement string-like class using tuple or list. Does anyone know about some example codes of pure python implementation of string-like class? Because I am trying to use Python for a text processing which is composed of a large character set. As the character set is wider than UTF-16(U+10FFFF), I can't use Python's native unicode string class.
