Perhaps you should try some spelling variations:
"variance functions study coding program" » "covariance functions study coding program" (Expand search), "variable functions study coding program" (Expand search), "covariance function study coding program" (Expand search), "variance functional study coding program" (Expand search), "variance function studies coding program" (Expand search), "variance functions study cloning program" (Expand search), "variance functions study loading program" (Expand search), "variance functions study cooling programs" (Expand search), "variance functions study coming program" (Expand search), "variance functions study according program" (Expand search), "variance functions study covering program" (Expand search)
"advanced python programming coding program" » "advanced python programming using program" (Expand search), "advanced python programming code program" (Expand search), "advanced python programming computing program" (Expand search), "advanced method programming coding program" (Expand search), "advanced path programming coding program" (Expand search), "advanced symphony programming coding program" (Expand search), "advanced python programming cloning program" (Expand search), "advanced python programming loading program" (Expand search), "advanced python programming cooling programs" (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 study coding program\") OR (\"advanced python programming coding program\"))~".
• Removing quotes may allow a broader search: (( variance functions study coding program ) OR ( advanced python programming coding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("variance functions study coding program") OR ("advanced python programming coding program"))*.
