Assuming the requirements specified in a different column of the pandas dataframe are binary (0 or 1), you can use the following code to calculate the overall count of zeroes:

import pandas as pd df = pd.read_csv('example.csv') # read csv file into dataframe count_zero = df[df['binary_col'] == 0]['value_col'].count() # count the 0 values in the value column based on binary column print(count_zero) # print output 

In this code, you would replace "example.csv" with the name of your input file, "binarycol" with the name of the column containing the binary values, and "valuecol" with the name of the column where the zeroes are counted. The code filters the dataframe using the condition df['binary_col'] == 0 to select only the rows where binarycol is 0 and then counts the number of zeros in the valuecol using .count(). The output is then printed.
