But if the example is "ABCDCDC" , then count is right... if you search for "CDC" explicitly.

"AB cdc DC" so CDC is just once in a string.

The docs for str.count explicitly mentions this behavior:

Return the number of non-overlapping occurrences of substring sub in the range [start, end]. Optional arguments start and end are interpreted as in slice notation.

See this answer for counting substrings with overlaps
