Define a function f in the MyContext` Context:

In[1]:=1
✖
https://wolfram.com/xid/0dskq-7e0nm
Out[1]=1
In[2]:=2
✖
https://wolfram.com/xid/0dskq-j5jw7v
Out[2]=2
In[3]:=3
✖
https://wolfram.com/xid/0dskq-j8alxw

Restore the context:

In[4]:=4
✖
https://wolfram.com/xid/0dskq-s71x2
Out[4]=4

The context is now what it was before Begin was used:

In[5]:=5
✖
https://wolfram.com/xid/0dskq-c5ci2p
Out[5]=5

Properties & Relations  (3)Properties of the function, and connections to other functions

Begin["cont`"] sets $Context to "cont`":

In[1]:=1
✖
https://wolfram.com/xid/0dskq-7m7isf
Out[2]=2
Out[3]=3

End restores $Context to its value before the matching Begin:

In[4]:=4
✖
https://wolfram.com/xid/0dskq-foci5r
Out[5]=5

Unlike BeginPackage, Begin does not modify $ContextPath:

In[1]:=1
✖
https://wolfram.com/xid/0dskq-f64hii
Out[1]=1

Similarly, End does not modify it, either:

In[2]:=2
✖
https://wolfram.com/xid/0dskq-54u8m
Out[2]=2

Begin does not alter the value of $ContextAliases:

In[1]:=1
✖
https://wolfram.com/xid/0dskq-097mdd
Out[1]=1

End restores $ContextAliases to its value before the matching Begin:

In[2]:=2
