Invalid syntax in Python script of rnaQUAST - python-2.7

Question

I have been trying to run a software, but since I am not an expert in python I do not know what this syntax error could be. I get the following error message:
Traceback (most recent call last):
File "rnaQUAST.py", line 29, in <module>
from metrics import TranscriptsMetrics
File "/NFS/home/ffalcon/TOOLS/rnaQUAST1.4.0/metrics/TranscriptsMetrics.py", line 6, in <module>
from general import UtilsCoverage

covered_isoform_fraction_max = {id_isoform: isoforms_covered_fraction[id_isoform] for id_isoform in ids_isoforms_max}

SyntaxError: invalid syntax

dict comprehension works python2.7 upwards. Based on your comment, I believe that you got the error from python2.6 as below:
Python2.6
Python 2.6.6 (r266:84292, Jan 22 2014, 09:42:36)

>>> mydict = {"a":1}
>>> mylist = ["a"]
>>> {x:mydict[x] for x in mylist}
File "<stdin>", line 1
{x:mydict[x] for x in mylist}

SyntaxError: invalid syntax
Python2.7
Python 2.7.10 (default, Oct 23 2015, 19:19:21)
[GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.0.59.5)] on darwin

>>> mydict ={"a":1}
>>> mylist=["a"]
>>> {x:mydict[x] for x in mylist}
{'a': 1}
Here's my solution:
>>> data = dict((x,mydict[x]) for x in mydict)
>>> data
{'a': 1}
