THEN HERE:


I need to return a dictionary from the list of dictionaries in Bittrex_Get_Market_Summaries, and I need to find that dictionary not by its index value but by it containing a 'MarketName': key value.

('\''+(Bittrex_Mrkt_0)['BaseCurrency']+'-'+(Bittrex_Mrkt_0)['MarketCurrency']+'\'')
'BTC-LTC'

That could be inserted after 'MarketName': but I don't know what to do beyond that. I'm still very new to Python. Maybe a for loop is what I'm looking for here?

---

In other words: I need information from BOTH of those links.

The first link gives the Active True/False and IsRestricted True/False information to the if statements.

Based on that, the Bid and Ask values are going to be pulled next for the same BTC-LTC pair.

So I can't go by the index in the list since they are totally different and will always possibly change.

I have to use 'BTC-LTC' as a way to search the second list of dictionaires, NOT the index.

Do you want this ?

[dn237]

I'm really grateful for someone trying to understand that mess of a post I made earlier but I think I was more tired than I realized and just posted a confusing mess lol.

That's not what I am looking for.

I need to search Bittrex_Get_Market_Summaries for 'MarketName': 'BTC-LTC' rather than index 0.

How do I do that?

---

Also what gets returned should be the entire dictionary containing 'MarketName': 'BTC-LTC'.

So I need to search through all of Bittrex_Get_Market_Summaries for a dictionary containing the key value 'MarketName': 'BTC-LTC' and have that dictionary print or whatever.

[heiner55]

I thought I have done this:

 
for market in markets:
    if market['IsActive'] == True  and  market['IsRestricted'] == False:
        ticker = market['BaseCurrency'] + '-' + market['MarketCurrency']
        print(ticker, end="")
        for market_sum in markets_sum:
            if ticker == market_sum['MarketName']:
                print(" found", end="")
                break
        print(".")

[dn237]

I thought I have done this:

 
for market in markets:
    if market['IsActive'] == True  and  market['IsRestricted'] == False:
        ticker = market['BaseCurrency'] + '-' + market['MarketCurrency']
        print(ticker, end="")
        for market_sum in markets_sum:
            if ticker == market_sum['MarketName']:
                print(" found", end="")
                break
        print(".")

Maybe I just don't understand that code but the output seems different than what I'm needing.

The IsActive and IsRestricted comes from Bittrex_Markets.

So if say BTC-LTC is True and False for those, then I need to search Bittrex_Get_Market_Summaries for a dictionary containing the key value 'MarketName': 'BTC-LTC' to print that entire dictionary.

This next bit is unrelated, but once I have that entire dictionary I will be using the bid and ask from it.

I don't need code just saying if any of them are found or not. If say 'BTC-LTC' is both True and False, I already know it is somewhere in the second variable Bittrex_Get_Market_Summaries.

I think it may be what I need. I think found can be changed to return the dictionary. I'm very new to Python so I apologize for being inept.
