How do I get the value of 2^(column of pandas dataframe) in another col of a dataframe.

For example:

Value 2^Value
0 1
1 2
Solution

  • You can use numpy.power :

    import numpy as np

df["2^Value"] = np.power(2, df["Value"])

    Or simply, 2 ** df["Value"] as suggested by @B Remmelzwaal.

    Output :

    print(df)

   Value  2^Value
0      0        1
1      1        2
2      3        8
3      4       16
