greater than x > y x.__gt__(y) greater than or equal to x >= y x.__ge__(y) truth value in a boolean context if x: x.__bool__() ☞If you define a __lt__() method but no __gt__() method, Python will use the __lt__() method with operands swapped. However,...
Evaluate expression EXP and assign result to variable VAR, using assignment syntax appropriate for the current language (VAR = EXP or VAR := EXP for example). VAR may be a debugger "convenience" variable (names starting with $), a register (a few standard names starting with $), or an ...
x >= y # x is greater than or equal to y x <= y # x is less than or equal to y x is y # x is the same as y x is not y # x is not the same as y Although these operations are probably familiar to you, the Python symbols are different from the mathematical symbols for...

Programs that are compiled into native machine code tend to be faster than interpreted code. This is because the process of translating code at run time adds to the overhead, and can cause the program to be slower overall. Disadvantages of compiled languages ...
