This function saves its execution context and, if necessary, continues execution immediately.
For example, the Fibonacci function:

Def Fibonacci ():

While True:
Yield b

Brief introductionThis article is intended to describe how to define a Python source file encoding. The Python interpreter can parse the current file based on the encoding information specified. Typically, this approach improves the parser's recognition of Unicode-encoded source files and supports writing Unicode encodings, such as using UTF-8 in an editor that supports Unicode encoding.ProblemIn python2.1,
