6. How do you handle nested data in a string while converting to a list? Use json.loads() to parse structured JSON data into nested lists. Here’s an example: import json string = '{"apple": ["red", "green"], "banana": ["yellow", "green"]}' nested_list = json.loads(string...
2. Join String When you join a string with a separator in python, it separates each character in a string by the specified delimiter and returns a new string. Here is an example. # Create two stringsstr1="ABC"str2="XYZ"# Join string with characterstr3=",".join(str1)print(str3)#...
You can also convert the string to a list usingstring slicing. It initializes a string and defines a functionConvert()to perform the conversion. In theConvert()function, an empty listmylistis created. Then, the slicemylist[:0]is used to insert each character from the stringstringat the ...
