pass Statement
One Python statement not found in C is the pass statement. Because Python does not use curly braces to delimit blocks of code, there are places where code is syntactically required. We do not...

continue Statement
Whether in Python, C, Java, or any other structured language which features the continue statement, there is a misconception among some beginning programmers that the traditional continue statement “immediately starts the next iteration of...
break Statement
The break statement in Python terminates the current loop and resumes execution at the next statement, just like the traditional break found in C. The most common use for break is when some external...
range() function
The built-in function range() can turn your foreach-like for-loop back into one that you are more familiar with, i.e., counting from zero to ten, or counting from 10 to 100 in increments of 5....
Switch/Case Statement Proxy
Earlier in previous programs, we introduced the if-elif-else construct and indicated that Python did not support a switch/case statement. In many cases, an incredibly long set of if-elif-else statements can be replaced by a...
for Statement
The other looping mechanism in Python comes to us in the form of the for statement. Unlike the traditional conditional looping for statement found in mainstream third generation languages (3GLs) like C, Fortran, or...
Infinite Loops
One must use caution when using while loops because of the possibility that this condition never resolves to a false value. In such cases, we would have a loop that never ends on our...
while Statement
Python’s while is the first looping statement. In fact, it is a conditional looping statement. In comparison with an if statement where a true expression will result in a single execution of the if...
elif (a.k.a. else-if) Statement
elif is the Python else-if statement. It allows one to check multiple expressions for truth value and execute a block of code as soon as one of the conditions evaluates to true. Like the...
if else Statement
Like other languages, Python features an else statement that can be paired with an if statement. The else statement identifies a block of code to be executed if the conditional expression of the if...
