csv reads comma-separated values files
Functions
def read_all
read_all(source, comma=",", comment="", lazy_quotes=False, trim_leading_space=False, fields_per_record=0, skip=0) [][]string
read all rows from a source string, returning a list of string lists
parameters:
| name | type | description |
|---|---|---|
| 'source' | 'string' | input string of csv data |
| 'comma' | 'string' | comma is the field delimiter, defaults to "," (a comma). comma must be a valid character and must not be \r, \n, or the Unicode replacement character (0xFFFD). |
| 'comment' | 'string' | comment, if not "", is the comment character. Lines beginning with the comment character without preceding whitespace are ignored. With leading whitespace the comment character becomes part of the field, even if trim_leading_space is True. comment must be a valid character and must not be \r, \n, or the Unicode replacement character (0xFFFD). It must also not be equal to comma. |
| 'lazy_quotes' | 'bool' | If lazy_quotes is True, a quote may appear in an unquoted field and a non-doubled quote may appear in a quoted field. |
| 'trim_leading_space' | 'bool' | If trim_leading_space is True, leading white space in a field is ignored. This is done even if the field delimiter, comma, is white space. |
| 'fields_per_record' | 'int' | fields_per_record is the number of expected fields per record. If fields_per_record is positive, read_all requires each record to have the given number of fields. If fields_per_record is 0, read_all sets it to the number of fields in the first record, so that future records must have the same field count. If fields_per_record is negative, no check is made and records may have a variable number of fields. |
| 'skip' | 'int' | number of rows to skip, omitting from returned rows |
def write_all
write_all(source,comma=",") string
write all rows from source to a csv-encoded string
parameters:
| name | type | description |
|---|---|---|
| 'source' | '[][]string' | array of arrays of strings to write to csv |
| 'comma' | 'string' | comma is the field delimiter, defaults to "," (a comma). comma must be a valid character and must not be \r, \n, or the Unicode replacement character (0xFFFD). |
