PfsDocument

PfsDocument(self, data, *, encoding='cp1252', names=None, unique_keywords=False)

Create a PfsDocument object for reading, writing and manipulating pfs files.

Parameters

Name	Type	Description	Default
data	TextIO \| PfsSection \| Mapping[str \| PfsSection, Any] \| str \| Path	Either a file name (including full path) to the pfs file to be read or dictionary-like structure.	required

clear

PfsDocument.clear()

Remove all items from the PfsSection.

copy

PfsDocument.copy()

Return a deep copy of the PfsDocument.

find_replace

PfsDocument.find_replace(old_value, new_value)

Update recursively all old_value with new_value.

from_dataframe

PfsDocument.from_dataframe(df, prefix)

Create a PfsSection from a DataFrame.

Parameters

Name	Type	Description	Default
df	pd.DataFrame	data	required
prefix	str	section header prefix	required

Examples

import pandas as pd
import mikeio
df = pd.DataFrame(dict(station=["Foo", "Bar"],include=[0,1]), index=[1,2])
df

	station	include
1	Foo	0
2	Bar	1

mikeio.PfsSection.from_dataframe(df,"STATION_")

[STATION_1]
   station = 'Foo'
   include = 0
EndSect  // STATION_1
[STATION_2]
   station = 'Bar'
   include = 1
EndSect  // STATION_2

from_text

PfsDocument.from_text(text)

Create a PfsDocument from a string.

get

PfsDocument.get(key, default=None)

Return the value for key if key is in the PfsSection, else default. If default is not given, it defaults to None, so that this method never raises a KeyError.

items

PfsDocument.items()

Return a new view of the PfsDocument’s items ((key, value) pairs).

keys

PfsDocument.keys()

Return a list of the PfsDocument’s keys (target names).

pop

PfsDocument.pop(key, default=None)

If key is in the dictionary, remove it and return its value, else return default. If default is not given and key is not in the dictionary, a KeyError is raised.

search

PfsDocument.search(text=None, *, key=None, section=None, param=None, case=False)

Find recursively all keys, sections or parameters matching a pattern.

NOTE: logical OR between multiple conditions

Parameters

Name	Type	Description	Default
text	str	Search for text in either key, section or parameter, by default None	`None`
key	str	text pattern to seach for in keywords, by default None	`None`
section	str	text pattern to seach for in sections, by default None	`None`
param	(str, bool, float, int)	text or value in a parameter, by default None	`None`
case	bool	should the text search be case-sensitive?, by default False	`False`

Returns

Name	Type	Description
	PfsSection	Search result as a nested PfsSection

to_dataframe

PfsDocument.to_dataframe(prefix=None)

Output enumerated subsections to a DataFrame.

Parameters

Name	Type	Description	Default
prefix	str	The prefix of the enumerated sections, e.g. “OUTPUT_”, which can be supplied if it fails without this argument, by default None (will try to “guess” the prefix)	`None`

Returns

Name	Type	Description
	pd.DataFrame	The enumerated subsections as a DataFrame

Examples

pfs = mikeio.read_pfs("../data/pfs/lake.sw")
pfs.SW.OUTPUTS.to_dataframe(prefix="OUTPUT_")
