saving multiple plots to pdf with PdfPages python

I'm trying to save my output (70+ graphs) from jyputer notebook into pdf file. No errors or whatsoever, but only the first graph is being exported. Can anyone please help me to understand what is wrong?

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.backends.backend_pdf

pdf = matplotlib.backends.backend_pdf.PdfPages("output.pdf")
df_num = df.select_dtypes(include = ['float64', 'int64'])

with PdfPages(r'output.pdf') as export_pdf:
    fig = plt.figure(figsize=(12,12))
    for col in df_num.columns:
        hist = df_num[col].hist(bins=10)
        print("Plotting for column {}".format(col))
        plt.title("{}".format(col), fontsize=20) 
        plt.show()        
    export_pdf.savefig(fig)

OK, eventually i figured it out. here is my solution:

with PdfPages(r'output_dist.pdf') as export_pdf:
    
    for col in df_f.columns:
        fig = plt.figure(figsize=(12,12))
        hist = df_f[col].hist(bins=10)
        print("Plotting for column {}".format(col))
        plt.title("{}".format(col), fontsize=20) 
        plt.show()
        
        export_pdf.savefig(fig)
