pynbody.util.ExecutionControl

class pynbody.util.ExecutionControl

Bases: object

Class to control execution flow in a with statement.

For example, one may use this to control whether a block of code should be executed or not, based on some condition which is externally controlled at runtime.

Example:

c = ExecutionControl()
with c:
 if c:
     print("This will be executed")
if c:
  print("This will not be executed")

This is used for implementing the various execution control mechanisms in pynbody.snapshot.simsnap.SimSnap.
