Reorder expressions in order to save whitespace
Consider the following code:
if c=='U':c='X'
The space between if and c obviously cannot be removed, as that would merge them to the identifier ifc. However by reversing the order of the arguments to ==, the space becomes removable:
if'U'==c:c='X'
As user noted in the comments, another place where whitespace can be saved is between a number and a following keyword. For example, in
if 2+x in{a,b,c}:x=0
the space between x and in cannot be simply removed. However reordering the sum allows to remove it anyway:
if x+2in{a,b,c}:x=0
