However, due to malformed data, it may not. We don't want an all or nothing approach, so we allow for small variations in this number. 1) build a table of the frequency of each character on every line. 2) build a table of freqencies of this frequency (meta-frequency?), e.g. 'x occurred 5 times in 10 rows, 6 times in 1000 rows, 7 times in 2 rows' 3) use the mode of the meta-frequency to determine the /expected/ frequency for that character 4) find out how often the character actually meets that goal 5) the character that best meets its goal is the delimiter For performance reasons, the data is evaluated in chunks, so it can try and evaluate the smallest portion of the data possible, evaluating additional chunks as necessary. s i i i i c C s | d | d j o | p | S( Ni ( R\ R] ( R\ R] ( ( R R^ 4 s c C s d | d | d f S( Ni i ( R\ R] ( R\ R] ( ( R R^ : s f1.0f0.90000000000000002f0.01s %c R N( R i () t filterR Rh t splitRG t ranget ct chrt asciit minR! t chunkLengtht iterationt charFrequencyt modesR_ t startt endt linet charRH t metaFrequencyt countt freqRE t itemsRn t removet modeListt floatt totalt consistencyt thresholdRF t vRU RY R' R RQ R; ( R Rh RU R~ R} R‡ R… Rt R€ R{ R_ Rz Rv RY Rˆ Rx R| R; Rr Ry R' R RF Rw RG Rƒ R† ( ( R RV sz - ( "/* **c C s* t t | ƒ | i | ƒ ƒ } | i ƒ } t | ƒ } h } x t | ƒ D] } d | | <qI Wd } x | D]} | d j o Pn | d 7} t | ƒ | j o qj n x | i ƒ D]´ } xY t t t t g D]5 } y | | | ƒ PWqÌ t t f j o qÌ XqÌ Wt | | ƒ } | t j o t } n | | | j o* | | d j o | | | <qg| | =q³ q³ Wqj Wd } x¨ | i ƒ D]š \ } } t | ƒ t d ƒ j o3 t | | ƒ | j o | d 7} q | d 8} q‚y | | | ƒ Wn# t t f j o | d 7} q‚X| d 8} q‚W| d j S( Ni i i ( R t StringIORT R RW t rdrR7 t headerR! t columnst columnTypesRq t iR t checkedR8 RE t colt intt longR„ t complext thisTypeRC t OverflowErrort hasHeaderR t colTypet typet TypeError( R RT R‹ R— R8 R R RŒ RŽ RŠ R” R R– ( ( R t has_headerj sX ( R* R+ t __doc__R R RW RS RV Rš ( ( ( R R ¡ s @ e( R› Rb t _csvR R R R R R R R R R R R t cStringIOR‰ t ImportErrort __all__R R R R R R“ t NameErrorR„ R ( R R R R‰ R RŸ R R R R R R“ R R R R› R R Rb R R R R ( ( R t ? s& U<: !
