python filtering based on type of data

Question

Hi!
Does somebody know, how to filter series (there are different types in series: int, str, float) in python to get only values, which are integers?

I have next code:

s = pd.Series(data=['1', 2, 3.1, 'hi!', 5, -512, 12.42, 'sber', 10.10, 98],
index=range(2, 12))

So I understand how to get type of each value in series.
For example:

type(s[3]) ---> int

But how to do it for series?

Answer 1

Guys, the question is specific to pandas datatype Series.

You can filter a pandas series by a boolean array. So first you can determine which indices contain int type, and pass this as a slice to the series.

int_filter = s.apply(lambda e: type(e) == int)
print(s[int_filter])

I am not sure if this is what you are looking for:

# comprehension:
data=['1', 2, 3.1, 'hi!', 5, -512, 12.42, 'sber', 10.10, 98]
res = [val for val in data if isinstance(val, int)]

# filter:
res2 = list(filter(lambda x: isinstance(x, int), data))
print(res2)
print(res)

Just... filter()
