Parsers

PyLabware utility functions for reply parsing

PyLabware.parsers.researcher(reply, *args)

This is a wrapper function for reply parsing to provide consistent arguments order.

Parameters:

reply – Reply to parse with regular expression.

Returns:

Regular expression match object.

Return type:

(re.Match)

PyLabware.parsers.slicer(reply, *args)

This is a wrapper function for reply parsing to provide consistent arguments order.

Parameters:

reply (str) – Sequence object to slice.

Returns:

Slice of the original object.

Return type:

(any)

PyLabware.parsers.splitter(reply, separator, *slice_positions)

This is a combination of str.split() followed by slicing.

Allows to avoid using RegExes for simple cases.

Parameters:

• reply (str) – String to process

• separator (str) – Sparator for str.split().

PyLabware.parsers.stripper(reply, prefix=None, suffix=None)

This is a helper function used to strip off reply prefix and terminator. Standard Python str.strip() doesn’t work reliably because it operates on character-by-character basis, while prefix/terminator is usually a group of characters.

Parameters:

• reply (str) – String to be stripped.

• prefix – Substring to remove from the beginning of the line.

• suffix – Substring to remove from the end of the line.

Returns:

Naked reply.

Return type:

(str)
