Native string operations#

These str operations have fast, optimized implementations. Other string operations use generic implementations that are often slower.

Construction#

  • String literal

  • str(x: int)

  • str(x: object)

Operators#

  • Concatenation (s1 + s2)

  • Indexing (s[n])

  • Slicing (s[n:m], s[n:], s[:m])

  • Comparisons (==, !=)

  • Augmented assignment (s1 += s2)

Methods#

  • s1.endswith(s2: str)

  • s.join(x: Iterable)

  • s.replace(old: str, new: str)

  • s.replace(old: str, new: str, count: int)

  • s.split()

  • s.split(sep: str)

  • s.split(sep: str, maxsplit: int)

  • s1.startswith(s2: str)
