resets the current context.
Examples

Define a function f in the MyContext` Context:
f will generally be hidden in the restored context:
Applications (1)
Make symbols used for package function definitions private, reducing the possibility for conflict:
Any use of the symbol f in the package context ensures that f is created in that context:
When the context given to Begin starts with ` it extends from the current context:
Since the symbol f is in the package context, the function works after EndPackage:
You can see that the other variable uses the private context:
Properties & Relations (3)
Begin["cont`"] sets $Context to "cont`":
End restores $Context to its value before the matching Begin:
Unlike BeginPackage, Begin does not modify $ContextPath:
Similarly, End does not modify it, either:
Begin does not alter the value of $ContextAliases:
End restores $ContextAliases to its value before the matching Begin:
