python - Convert list containing tuple to string -



python - Convert list containing tuple to string -

i have list containing tuples. need convert entire list string compression. code worked fine in python 2.7:

tt = '{}'.format(tt)

but in python 2.6 next error:

hist = '{}'.format(hist) valueerror: 0 length field name in format

the info in tt looks [(2, 3, 4), (34, 5, 7)...]

any workaround this, apart upgrading python version?

put index in replacement field:

tt = '{0}'.format(tt)

or use:

tt = str(tt)

which back upwards versions of python prior introduction of str.format in 2.6.

demo:

>>> tt = [(2, 3, 4), (34, 5, 7)] >>> "{0}".format(tt) '[(2, 3, 4), (34, 5, 7)]' >>> str(tt) '[(2, 3, 4), (34, 5, 7)]'
