In Python, you can specify an else statement to a for loop or a while loop. The else block is executed if a break statement is not used.
forloop:Iterates over a sequence. whileloop:Runs as long as a condition is true. Example: # For loop for i in range(3): print(i) # While loop x = 0 while x < 3: print(x) x += 1 12. What are Python’s conditional statements?
In Python you can use the codeop module, which approximates the parser's behavior sufficiently. IDLE uses this, for example. The easiest way to do it in C is to call PyRun_InteractiveLoop() (perhaps in a separate thread) and let the Python interpreter handle the input for you. You ca...
