Creating an if statement in python from one string

I'm working on a project that allows users to define filters to sort data in a csv file. They can create as many or as few filters as they want so I am trying to create an if statement from a string that will get longer as users define more filters.

I have an output for my string variable which is this: row[0]=="6/1/2014 0:00:00"

So for simplicity sake I'll just hard code that into a variable name in the sample code below

The problem is that it doesn't correctly evaluate this if statement. It returns every row of the file.

f = open("somefile.csv", "r")
r = csv.reader(f)

statement = 'row[0]=="6/1/2014 0:00:00"'
for row in r:

    if statment:
       print(row)
