Python csv file determine data type -

-

new student here please excuse ignorance, have searched lot , not found solution problem. needing import csv file mixed data types [ int, float, , string], determine data type, maths on ints , floats.

the problem csv reader converts strings ( or strings?). can try , convert float, , if throws error message know string, how tell if float, program needs determine between two?

i allowed import csv , no others. second first-year python subject, , not sure how this.

edit, found 1 answer seems similar problem, still returns wrong answers, ints usually, not always, still returned string type:

 import csv    tests = [     # (type, test)     (int, int),     (float, float),     ]    def gettype(value):      typ, test in tests:      try:          test(value)          return typ      except valueerror:          print 'value error'          continue  # no match  return str      file = open('adult.csv')     reader = csv.reader(file)     filename = 'output.xml'      text = open(filename, 'w')     text.write('<?xml version="1.0"?>')      text.write('<!doctype summary [')       headers = reader.next()      in headers:      print '<name>'      print      print '</name>'      print '<datatype>'  in i[1]:     print gettype[a]   #for row in fields:   #  text = row[2]   #  print type(text) print '</datatype>' #for value in i:    # print type(value)     print '<!element summary\n\n>' #text.write('<element>')

ok sorry everybody, think found code think work:

determine type of value represented string in python

should have searched harder, although still not reliably giving correct type

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
