Perhaps you should try some spelling variations:
"advanced functions in python programming" » "advanced selections in python programming" (Expand search), "advanced solutions in python programming" (Expand search), "advanced functionality in python programming" (Expand search), "advanced functions _ python programming" (Expand search)
"variance functions method coding program" » "covariance functions method coding program" (Expand search), "variable functions method coding program" (Expand search), "covariance function method coding program" (Expand search), "variance functions methods coding program" (Expand search), "variance function method coding program" (Expand search), "variance functional method coding program" (Expand search), "variance functions method cloning program" (Expand search), "variance functions method loading program" (Expand search), "variance functions method cooling programs" (Expand search), "variance functions method cooling program" (Expand search), "variance functions method fnding program" (Expand search), "variance functions method according program" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"variance functions method coding program\") OR (\"advanced functions in python programming\"))~".
• Removing quotes may allow a broader search: (( variance functions method coding program ) OR ( advanced functions in python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("variance functions method coding program") OR ("advanced functions in python programming"))*.
