What operations are supported by most sequences in Python?

• Indexing (s[i])
• Slicing (s[i:j], s[i:j:k])
• Iteration (for x in s:)
• Length (len(s))
• Membership check (x in s, x not in s)
• Concatenation (s + t)
• Repetition (s * n, n * s)
• Minimum value (min(s))
• Maximum value (max(s))
• Index search (s.index(x[, i[, j]]))
• Count of occurrences (s.count(x))

Mutable sequences (such as lists) also support:

• Assignment by index (s[i] = x)
• Slice assignment (s[i:j] = t)
• Deletion of an element by index (del s[i])
• Slice deletion (del s[i:j])
• In-place modification (s += t, s *= n)

Some operations may have different implementations or efficiencies depending on the specific sequence type. For example, searching for an element in a list may be slower than in other data structures.
