Nested List Loop












3















I would like to loop the nest list ['sally','joe'] in the example shown below.



data = ['joe','mike',['sally','joe'],'phil']


I attempted the following:



for i in data:

    for j in (i):

        if type(j) == '<class '+"'list'>":    

            print(j)





python list class for-loop if-statement

  • Please show your desired output. Is it ['sally','joe'] or is it joe mike sally joe phil (with newlines between)?

Why not just isinstance:



for i in data:

    if isinstance(i,list):

        print(i)


Now the output is:



['sally', 'joe']

    You would need to use:



    if type(j) == list:
    
    print(j)


    It doesn't currently work because type(j) returns an object of class type, not a string. You might think it is a string because when printing it in a REPL interpreter, you might see the repr(..) version.

            Is it possible to collect Nectar points via Trainline?

            Image
            2 Since I am not eligible for any Railcard, the only available discount/bonus scheme is Nectar Card for me. GWR, SWR, LNER and Virgin Trains allow to collect Nectar points and I have already linked a card to my GWR account. A friend suggested me to use Trainline App, because it can search for bus tickets either. I had a look at the application, but could not see any option for Nectar.
