Parameters, but offers a default value for some of them: For example, given a function which accepts several Shorter than they appear this is turn can lead to confusing, or even Implicit String concatenation leads to tuples and lists which are More standard Python idioms, such or "".join. The strings can be joined (and still recognized as immutable) using Using a (run-time) function call to store into a variable. In C, implicit concatenation is the only way to join strings without Languages should be treated as a tie-breaker, rather than a Programmers will also be familiar with C, so compatibility between Is a useful default, but Special Cases need to be justified based on Many Python parsing rules are intentionally compatible with C. State with confidence the implicit operator precedence and under whatĬircumstances it is computed when the definition is compiled versus Of those who both know about it and use it, very few could Those who do know about it, a large portion never use it or habituallyĪvoid it. Of current users do not even know about implicit concatenation. Important for letting the language “fit in your head”. Grammar and simplify a user’s mental picture of Python. Implicit string concatenation shouldīe dropped in favor of existing techniques. ![]() One goal for Python 3000 should be to simplify the language by This PEP proposes to eliminate implicit string concatenation based Useful for python, and should be eliminated. While this hasīeen generally useful, there are some individual rules which are less Python inherited many of its parsing rules from C. There wasn’t enough support in favor, theįeature to be removed isn’t all that harmful, and there are some use Raymond Hettinger Status : Rejected Type : Standards Track Created : 2 Post-History : 2, 3, 0 Toggle light / dark / auto colour theme PEP 3126 – Remove Implicit String Concatenation Author : Jim J.
