Code:
function _() { echo 'hello word'; } Output:
Fatal error: Cannot redeclare _()
I haven't defined this function _ before, then why I am getting this error?

Python automatically stores the value of the last expression in the interpreter to a particular variable called "_." You can also assign these value to another variable if you want. You can use it as a normal variable.
Updated on July 03, 2019. The dollar sign ($) and the underscore (_) characters are JavaScript identifiers, which just means that they identify an object in the same way a name would. The objects they identify include things such as variables, functions, properties, events, and objects.
Enforced by the Python interpreter. Double Leading and Trailing Underscore( __var__ ): Indicates special methods defined by the Python language. Avoid this naming scheme for your own attributes. Single Underscore( _ ): Sometimes used as a name for temporary or insignificant variables (“don't care”).
A single leading underscore in front of a variable, a function, or a method name means that these objects are used internally. This is more of a syntax hint to the programmer and is not enforced by the Python interpreter which means that these objects can still be accessed in one way on another from another script.
_() is an alias for gettext.
