       Print descriptive statistics for each column in a CSV file.

   positional arguments:
       FILE   The CSV file to operate on. If omitted, will accept input as piped data via STDIN.

   options:
       -h, --help
              show this help message and exit

       -d DELIMITER, --delimiter DELIMITER
              Delimiting character of the input CSV file.

       -t, --tabs
              Specify that the input CSV file is delimited with tabs. Overrides "-d".

       -q QUOTECHAR, --quotechar QUOTECHAR
              Character used to quote strings in the input CSV file.

       -u {0,1,2,3}, --quoting {0,1,2,3}
              Quoting style used in the input CSV file. 0 = Quote Minimal, 1 = Quote All, 2 = Quote Non-numeric,
              3 = Quote None.

       -b, --no-doublequote
              Whether or not double quotes are doubled in the input CSV file.

       -p ESCAPECHAR, --escapechar ESCAPECHAR
              Character used to escape the delimiter if --quoting 3 ("Quote None") is specified  and  to  escape
              the QUOTECHAR if --no-doublequote is specified.

       -z FIELD_SIZE_LIMIT, --maxfieldsize FIELD_SIZE_LIMIT
              Maximum length of a single field in the input CSV file.

       -e ENCODING, --encoding ENCODING
              Specify the encoding of the input CSV file.

       -L LOCALE, --locale LOCALE
              Specify the locale (en_US) of any formatted numbers.

       -S, --skipinitialspace
              Ignore whitespace immediately following the delimiter.

       --blanks
              Do not convert "", "na", "n/a", "none", "null", "." to NULL.

       --null-value NULL_VALUES [NULL_VALUES ...]
              Convert this value to NULL. --null-value can be specified multiple times.

       --date-format DATE_FORMAT
              Specify a strptime date format string like "%m/%d/%Y".

       --datetime-format DATETIME_FORMAT
              Specify a strptime datetime format string like "%m/%d/%Y %I:%M %p".

       -H, --no-header-row
              Specify that the input CSV file has no header row.  Will create default headers (a,b,c,...).

       -K SKIP_LINES, --skip-lines SKIP_LINES
              Specify  the  number  of  initial  lines  to  skip before the header row (e.g. comments, copyright

       -v, --verbose
              Print detailed tracebacks when errors occur.

       -l, --linenumbers
              Insert a column of line numbers at the front of the output. Useful when piping to  grep  or  as  a
              simple primary key.

              1-based numbering.

       -V, --version
              Display version information and exit.
