I am new to Python. I have a data frame as shown below. This is a CSV file. I need to select all rows which contain Frequency values 0.8 and 0.6. I wrote the codes as shown but it is throwing an error.

df_new = df[df['Frequency'] == 0.8 & df['Frequency'] == 1.6 ]

Below is the last line from the error I received.

"TypeError: Cannot perform 'rand_' with a dtyped [float64] array and scalar of type [bool]"

I ran the below code

df_new = df[(df['Frequency'] == 0.8) & (df['Frequency'] == 1.6) ]

It is nt showing any error but values are not coming.it is showing only the name of columns .Please see the bwloe image
