Python equivalent of the R operator "%in%"

FWIW: without having to call pandas, here's the answer using a for loop and list compression in pure python

x = [2, 3, 5] 
y = [1, 2, 3]

# for loop
for i in x: [].append(i in y)

Out: [True, True, False]


# list comprehension
[i in y for i in x]

Out: [True, True, False]

Pandas comparison with R docs are here.

s <- 0:4
s %in% c(2,4)

The isin method is similar to R %in% operator:

In [13]: s = pd.Series(np.arange(5),dtype=np.float32)

In [14]: s.isin([2, 4])
Out[14]: 
0    False
1    False
2     True
3    False
4     True
dtype: bool
