The operators could be of type integer, float, double, string, relational or logical. First, Puppet checks whether the control and array are the same length, then each corresponding element is compared using these same case matching rules. Each option is automatically quoted when passed to the install command. In this post we will see how we can solve this challenge in Python. You can use parameters to restrict which values Array matches. Please note the fact that this is the default location where puppet will look for hiera config file.

Result can also be an array of hashes but a hash with the same keys as in the connection hash would be nice. It's not required and the in operator is supposed to return the booleon true if the value left of the in operator is in the value of the right, which it is. To match, the control value and the case must have the same keys, and each corresponding value is compared using these same case matching rules. It does not matter which backend that is, there can even be several of them. Ask Question Asked 9 years, 2 months ago. case statements come in handy when you want to execute different code depending on the value of some expression. case statements come in handy when you want to execute different code depending on the value of some expression. The only difference it has from lambda expressions is that this uses direct reference to the method by name instead of providing a delegate to the method.
