matches an optional x character (in other words, it matches an x zero or one times). • x* matches x zero or more times. • x+ matches x one or more times. • x{n,m} matches an x character at least n times, but not more than m times. • (a|b|c) matches exactly ...
Statically typed languages type-check at compile time and the type can NOT change. Python is a good general-purpose, high-level language. Its design makes it very reada‐ ble, which is more important than it sounds. Every computer program is written only once, but read and revised many ...

Strictly speaking, strings are sequences of one-character strings; other types of sequences include lists and tuples, covered later. Sequence Operations As sequences, strings support operations that assume a positional ordering among items. For example, if we have a four-character string, we can...
A helper function is provided to generate a 32-character base32 secret, compatible with Google Authenticator and other OTP apps: pyotp.random_base32() Some applications want the secret key to be formatted as a hex-encoded string: pyotp.random_hex() # returns a 40-character hex-encoded secret...
