Basic Examples

Swap the cases in a string:

In[1]:=

Out[1]=

Scope

SwapCase automatically threads over a list of strings:

In[2]:=

Out[2]=

Properties and Relations

SwapCase can be programmed by using LowerCaseQ or UpperCaseQ and the functions ToUpperCase and ToLowerCase:

In[3]:=

Out[4]=

The implementation of SwapCase is many times faster, though:

In[5]:=

Out[6]=

Possible Issues

For nearly all strings, SwapCase is an involutory function:

In[7]:=

Out[8]=

There are a few exceptions:

In[9]:=

Out[10]=

Some strings will get longer after swapping cases:

In[11]:=

Out[11]=
