Im getting below error and please let me know how to convert data from csv into list.
TypeError: can only concatenate str (not "list") to str

Answer 1

added some lines to create the Book1.csv file and write two lines into it

your problem in the last for loop was that you were attempting to concatanate string with list

when you read lines from csv a which look like this:

|first|row|
|second|row|

the data is loaded like this:
data = [
['first', 'row'],
['second', 'row']
]

so one thing you can do is to join the sub-lists which will generate from ['first', 'row'] this string: 'first row'
