I don;t know what Jinja is but...

When you say 'print', where do you want to print it?
It seems you are using Flask so presumably the output goes to a web
page? So presumably you really want to output a string? Or do you
literally want to print to the console?

If you want a string from a list of values you can use join():

s = ' '.join([str(n) for n in outputList])

If you want to print to console you can use

for n in outputList:
   print n, # note the comma

in Python v2 or

for n in outputList:
print (n, end=' '))

in Python v3

or just combine the techniques:

s = ' '.join([str(n) for n in outputList])
print(s)
