如何检查字符串列表中的int列表？

Question

I have 2 defauldict(list); one of them only display the number and another one contain the whole line of text.

I have list of int (lookup)

[112, 896, 455, 1164, 1164, 336, 386, 521, 1011, 1033]

and list of string (description)

[['ZNF91', 'Q05481', 'VAR_057393', 'p.Tyr112His', 'Polymorphism', 'rs296091', '-'],
 ['ZNF91', 'Q05481', 'VAR_057394', 'p.Thr896Ala', 'Polymorphism', 'rs296093', '-'],...]

I am trying to come up with if statement to check while i run the program, basically, when i use number that match the line, i want to print the line of that string for example, if i use number 112, which match the first line (p.Tyr112His), i want to have it print the whole line that contains p.Tyr112His; which is:

'ZNF91', 'Q05481', 'VAR_057393', 'p.Tyr112His', 'Polymorphism', 'rs296091', '-'.

Answer 1

Looking at the revision history for this question, it appears that you are building the list of integers and the list of strings at the same time while iterating over a csv file. If that's the case, you might want to consider a slightly different data structure:

data = defaultdict(list)
with open(csvfile) as f:
    reader = csv.reader(f)
    for line in reader:
        number = ...  #parse the number from the line here
        data[number].append(line)

Now if you want access to all of the lines which contain the number 112, you can just do:

for line in data[112]:
   print (line)

If you need the list of numbers, you can get that easily: list(data.keys()) (or just data.keys() if you're using python 2.x)

Answer 2

There can be many different ways to do it. The following is one simple approach

list_of_ints=[112, 896, 455, 1164, 1164, 336, 386, 521, 1011, 1033]
list_of_strings=[['ZNF91', 'Q05481', 'VAR_057393', 'p.Tyr112His', 'Polymorphism', 'rs296091', '-'],
 ['ZNF91', 'Q05481', 'VAR_057394', 'p.Thr896Ala', 'Polymorphism', 'rs296093', '-']]
for ints in list_of_ints:
    for st in list_of_strings:
        if str(ints) in ','.join(st):
            print st


['ZNF91', 'Q05481', 'VAR_057393', 'p.Tyr112His', 'Polymorphism', 'rs296091', '-']
['ZNF91', 'Q05481', 'VAR_057394', 'p.Thr896Ala', 'Polymorphism', 'rs296093', '-']
