python , changing dictionary values with iteration [duplicate]

Question

I have the following:

max_id = 10
    for i in range(max_id):
        payload = "{\"text\": 'R'+str(i),\"count\":\"1 \",}"
        print(payload)

I want to iterate through this , and have the value of text be set to "R1", "R2" ... Upon debugging the output is:

{"text": 'R'+str(i),"count":"1",}

What am I doing wrong?

Double-check your double quotes. The syntax highlighting in your question might give you a hint. — Wander Nauta

Based on stackoverflow.com/questions/4450592/…, I've come up with payload = "{\"text\": %s,\"count\":\"1 \"}" % ("R"+str(i)) -Thank you — user1592380

for i in range(max_id):
    payload = "{\"text\": R"+str(i)+",\"count\":\"1 \",}"
    print(payload)

Problem with your double quotes.

Output:

{"text": R0,"count":"+i+ ",}
{"text": R1,"count":"+i+ ",}
{"text": R2,"count":"+i+ ",}
{"text": R3,"count":"+i+ ",}
{"text": R4,"count":"+i+ ",}
{"text": R5,"count":"+i+ ",}
{"text": R6,"count":"+i+ ",}
{"text": R7,"count":"+i+ ",}
{"text": R8,"count":"+i+ ",}
{"text": R9,"count":"+i+ ",}

My be you are looking for this one.

for i in range(10):
    payload = "{\"text\": R%s,\"count\":\"1 \",}" %(i)
    print(payload)

Thanks , I think people wanted the more pythonic method, please see my comment. Your way does work though

It's easier to read and write if you use single quotes as delimiters: payload = '{"text": R%s,"count":"1 ",}" %(i)

I'm working with windows so escaping helps
