DESCRIPTION¶
Loads a CSV file into a agate.csv.Reader object and then drops into a Python shell so the user can inspect the data however they see fit:
usage: csvpy [-h] [-d DELIMITER] [-t] [-q QUOTECHAR] [-u {0,1,2,3}] [-b]
[-p ESCAPECHAR] [-z FIELD_SIZE_LIMIT] [-e ENCODING] [-L LOCALE]
[-S] [--blanks] [--null-value NULL_VALUES [NULL_VALUES ...]]
[--date-format DATE_FORMAT] [--datetime-format DATETIME_FORMAT]
[-H] [-K SKIP_LINES] [-v] [-l] [--zero] [-V] [--dict] [--agate]
[--no-number-ellipsis] [-y SNIFF_LIMIT] [-I]
[FILE] Load a CSV file into a CSV reader and then drop into a Python shell. positional arguments:
FILE The CSV file to operate on. If omitted, will accept
input as piped data via STDIN. optional arguments:
-h, --help show this help message and exit
--dict Load the CSV file into a DictReader.
--agate Load the CSV file into an agate table.
--no-number-ellipsis Disable the ellipsis if the max precision is exceeded.
-y SNIFF_LIMIT, --snifflimit SNIFF_LIMIT
Limit CSV dialect sniffing to the specified number of
bytes. Specify "0" to disable sniffing entirely, or
"-1" to sniff the entire file.
-I, --no-inference Disable type inference when parsing the input. This
disables the reformatting of values.
This tool will automatically use the IPython shell if it is installed, otherwise it will use the running Python shell.
NOTE:
Due to platform limitations, csvpy does not accept file
input as piped data via STDIN.

EXAMPLES¶
Basic use:
- $ csvpy examples/dummy.csv
- Welcome! "examples/dummy.csv" has been loaded in a reader object named "reader". >>> next(reader) ['a', 'b', 'c']
As a dictionary:
$ csvpy --dict examples/dummy.csv Welcome! "examples/dummy.csv" has been loaded in a DictReader object named "reader". >>> next(reader) {'a': '1', 'c': '3', 'b': '2'}
As an agate table:
$ csvpy --agate examples/dummy.csv Welcome! "examples/dummy.csv" has been loaded in a from_csv object named "reader". >>> reader.print_table() | a | b | c | | ---- | - | - | | True | 2 | 3 |
