Reading CSV and returning array

python read csv into array
csv to array python
python read csv into list

Taking a video game design course and I've never had to use python before so I am very confused... I am tasked with the following :

read in the CSV file into Python and store its contents as a list of lists (or 2D list/array). To do so, you will make use of the CSV[1] library. The reading of the CSV file should be done as its own function - please create a function called readCSV(...) that takes in the file name as the argument and returns the 2D list.

As mentionned I have no previous coding experience with python. I have managed to do this so far and would greatly appreciate some support.

import csv

# reading each row and printing it 
def readCSV(fileName): 
    TwoDimList = []
    with open(fileName, 'r') as f:
        r = csv.reader(f, delimiter=',')
        for row in r:


entities = readCSV('entities.csv')              
print(entities)

Just append each row (which is a list of columns values) to your 2d list and return it in the end:

def readCSV(fileName): 
    two_dim_list = []  # snake case ftw (PEP8)
    with open(fileName, 'r') as f:
        r = csv.reader(f, delimiter=',')
        # next(r)  # skip header line if necessary
        for row in r:
            two_dim_list.append(row)
    return two_dim_list

The short version of that is:

def readCSV(fileName): 
    with open(fileName, 'r') as f:
        r = csv.reader(f, delimiter=',')
        # next(r)  # skip header line
        return list(r)

Reading a CSV File into an Array, A.simple tutorial to reading CSV files in Java arrays. In this tutorial, we'll look into different ways to read a CSV file into an return values;. Python Read CSV File into Array List: import csv file_CSV = open('crickInfo.csv') data_CSV = csv.reader(file_CSV) list_CSV = list(data_CSV) print list_CSV Save this program as readCSVFile.py and run it.

You can just call list on the reader to get the full 2d list:

def read_csv(file_name):
    with open(file_name) as f:
        return list(csv.reader(f))

This works because csv.reader is an iterable.

fgetcsv - Manual, Returns an indexed array containing the fields read. Note: A blank line in a CSV file will be returned as an array comprising a single null field, and will not be  read in the CSV file into Python and store its contents as a list of lists(or 2D list/array). To do so, you will make use of the CSV[1] library. The reading of the CSV file should be done as its own function - please create a function called readCSV()that takes in the file name as the argument and returns the 2D list. As mentionned I have no previous coding experience with python.

define a function to read csv and return list, and use it later in the program

def readCSVinList(fpath,fname):      
        with open(fpath+fname) as csv_file:        
               csv_reader=csv.reader(csv_file)        
         return list(csv_reader)  
f= readCSVinList("A:\\Test\\","test.csv")  
for row in f:  
    print(row)

str_getcsv - Manual, str_getcsv — Parse a CSV string into an array Returns an indexed array containing the fields read. Handy one liner to parse a CSV file into an array <?​php I wonder if there is a direct way to import the contents of a CSV file into a record array, much in the way that R's read.table(), read.delim(), and read.csv() family imports data to R's data frame? Or is the best way to use csv.reader() and then apply something like numpy.core.records.fromrecords()?
