all Python 3Byte sequencesfunction

bytearray.istitle

bytearray — is* checks

Checks that the sequence is in title case: each word starts with an uppercase ASCII letter followed by lowercase ones.

Syntax

ba.istitle(...)

The test is purely mechanical: every run of letters must start with an upper-case byte and continue in lower case — it has nothing to do with real headline capitalization rules. Any non-letter byte (digit, hyphen, punctuation) acts as a word boundary, so b'Hello2World' passes while b'HI There' fails on the second consecutive capital.

Examples

print(bytearray(b'Hi There').istitle())   # → True
print(bytearray(b'hi there').istitle())   # → False
print(bytearray(b'HI There').istitle())   # → False
print(bytearray(b'Hello2World').istitle())   # → True
print(bytearray(b'').istitle())   # → False
print(bytearray(b'hi there').title())   # → bytearray(b'Hi There')
