How to write to a .csv file without "import csv"
For an assignment I have to write some data to a .csv file. I have an implementation that works using Python's csv module, but apparently I am not supposed to use any imported libraries...
So, my question is how I could go about doing so? I am no expert when it comes to these things, so I am finding it difficult to find a solution online; everywhere I look import csv is being used.
Solution
Since csv stands for comma-separated values, you can create a file with the regular I/O built-in function that ends with .csv like:
f = open("demofile.csv", "w")
And then write to it:
f.write("1, 2, 3 ,4, 5\n 6, 7, 8, 9, 10")
Where each cell is separated by comma, and each row is separated by \n.
The result will look like this in MS Excel:
