Thanks for your PR - could you make the example one such that it shows the use of the default argument?

[oovk]

you mean this one right? @MarcoGorelli

df2 = df1.get("key") #key column is not available in dataframe 
print(df2)
None #Returns default value if not found.

I think, something like this (df is directly from the example you added)

In [9]: df.get(["temp_celsius","windspeed","temp_Kelvin"], default = "Some column missing")
Out[9]: 'Some column missing'

[MarcoGorelli]

have you run the validate_docstrings script? https://pandas.pydata.org/pandas-docs/stable/development/contributing_documentation.html#updating-a-pandas-docstring

[oovk]

yes. Tested the validate_docstrings and python make.py clean, python make.py --single pandas.DataFrame.get

[MarcoGorelli]

couple of comments, other than that looks good

[MarcoGorelli]

no need to assign to a new variable, let's just print the first one

Suggested change

	>>> df1 = df.get(["temp_celsius","windspeed"])
	>>> df1
	temp_celsius windspeed
	2014-02-12 24.3 high
	2014-02-13 31.0 high
	2014-02-14 22.0 medium
	2014-02-15 35.0 medium
	>>> df.get(["temp_celsius", "windspeed"])
	temp_celsius windspeed
	2014-02-12 24.3 high
	2014-02-13 31.0 high
	2014-02-14 22.0 medium
	2014-02-15 35.0 medium

[MarcoGorelli]

likewise, and dedent the result

Suggested change

	>>> df2 = df.get(["temp_celsius","temp_kelvin"], default = "default_value")
	>>> df2
	'default_value'
	>>> df.get(["temp_celsius", "temp_kelvin"], default = "default_value")
	'default_value'

These errors from validate_docstrings need fixing:

	flake8 error: E231 missing whitespace after ','
2     E251 unexpected spaces around keyword / parameter equals (2 times)

check https://www.python.org/dev/peps/pep-0008/

@MarcoGorelli How did you remove those errors? I have tried using autopep8 in vscode, It did nothing for me. Can u please explain a bit?
