python - Reading a list from file, then writing in a loop to solve for math equation -

-

i have list in file made of numbers.

i have command read number in list:

but having error:

typeerror: 'int' object not subscriptable

which don't understand 'int' issue.

with open('angles.txt', 'r') f:     print('angle sine         cosine      tangent')      number in f:         degree= int(number)         rad = math.radians(degree)         sin = math.sin(rad)          answer = degree[0]         print(str(answer), end = '')          print(format(math.sin(math.radians(rad)),'10.5f'),end='')         print(format(math.cos(math.radians(rad)),'10.5f'),end='')         print(format(math.tan(math.radians(rad)),'10.5f'),end='')

i can answer specific question int type error. problem these 2 lines don't make sense python:

degree = int(number)  answer = degree[0]

you're first defining degree integer, , trying access integer list! doesn't work.

Decoding a Python 2 `tempfile` with python-future -

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
