 If you want to catenate multiple pages using expressions you can use a [[https://pythonhosted.org/PyPDF2/Easy%20Concatenation%20Script.html#page-range|Page Range expression]].
-Remember to import the PageRange class
+To specify page ranges, you need to import the PageRange class

+then you can specify the range as a PageRange() object. For example, the range from page 13 (**REMEMBER: page indices start with zero.!**) to the last one can be written:
-  merger.append(pdf, pages=PageRange('130:-1'))
+  merger.append(inpdf, pages=PageRange('13:-1'))

+See below for a complete working python script with PyPDF2 and page ranges. Just set the in/out filenames, the starting/ending page numbers and run the script:
+  from PyPDF2 import PdfFileMerger, PdfFileReader, PageRange
+  infn = "infilename.pdf"
+  outfn = "outfilename.pdf"
+  startpage = 5 #set starting page in the pdf -1 (i.e. here we want to start from page 6)
+  endpage = -1  #last page
+  srcfile = PdfFileReader(infn, 'rb')
+  merger = PdfFileMerger()
+  page_range = str(startpage) + ':' + str(endpage)
+  merger.append(srcfile, pages=PageRange(page_range))
+  merger.write(outfn)
+And if you are using Ubuntu, remember to install pypdf2 package first
+  sudo apt install python3-pypdf2
