Operations and Operators
Operations are “basic” functions with their own syntax.
They have a special Operator (a sign or a word) that is the same as a function name. Unary Operators, operations which take one argument, are followed by their argument, and secondary operators are surrounded by their two arguments.
Here are some examples:
>>> 'GTnnAC' + 'GAATTC' 'GTnnACGAATTC' >>> 'GAATTC' * 3 'GAATTCGAATTCGAATTC' >>> 'n' in 'GTnnAC' 1This is only a simpler way of writing these functions provided by Python, because humans are in general more familiar with this syntax closely related to the mathematical formal language.
