python csv file reading writting.

Reading and writing to a csv file is fairly simple using python.As python has both reader() and writter() method is  easy to use.In the code below,the script is reading a csv file and appending  row values in different list.the csv file had data in this format



The code below take reads the csv file and take it name to a list and link to another list:

file_path = "path_of_your_csv_file"
shop = csv.reader(open(file_path, "rb"))
shop_list = []
file_name_list = []
rss_link_list = []
for d in shop_list:

And the writing to a csv file was interesting,I tried to write in a csv file and each time when a write was writting data but when a new write operation was executed previous data was erased.Actually,I was missing silly point the I didnt mention the data should be appended when writted.The code was as belows:

def csv_writer(data_list,file_path):
    import csv
    file_p = open(file_path, "wb")
    write_pattern = csv.writer(file_p, delimiter=",", quotechar=",")

In this method user have to pass data and the file path where the csv file will exists should be declared.

Run windows command line command using python

I was just playing with my python interpreter in my windows 7 system today and thinking what to do silly,fun.

Then just searched for the library in python which can be used to list windows directory/file.

The OS module is used in this case and it was simple.I put the windows command that I want to execute and passed it inside popen() .

windows = "dir"
command = os.popen(windows).read()
print command

Its simple 🙂

If any one have better solution than this please drop a line,that I can know that.
