import csv
with open("input.csv") as f:
    d1 = [row[0] for row in csv.reader(f)]
for x in d1:
    if 0<=int(x)<30:
        print("0<=x<30".format(x))
    elif 40<=int(x)<120:
        print("40<=x<120")

My code is shown above, and I am trying to save the output in a .csv file. Is there any solution to send data from elif to csv.writer?

Please do read the documentation. Everything that you need for this question is right there: docs.python.org/2/library/csv.html – Eduard Daduya 18 hours ago
    
As a note/hint: The way you word your problem also makes me worried about your understanding of if/elif. You do not "send" data from the elif statement. It is just a conditional statement and the code inside will be executed if the condition is fulfilled. The code inside the statement is no different than outside, so you do not have to "send" anything. – mwormser 17 hours ago
    
yes I know, but I question is how to write "someiterable" instead of x in d2.writerow(x)!? @Eduard Daduya – MOS 17 hours ago

Just add open('output.csv', 'w').write("40<=%s<120"%(x)) after your print statement in the elif section.

You just reopen with csv.writer like so:

d2 = csv.writer(f)
d2.writerow(x)

and read the documentation linked by @Eduard Daduya !!!!!!
