Blocks can be nested to arbitrary depth. Each indent defines a new block, and each outdent ends the preceding block. The resulting structure is straightforward, consistent, and intuitive.Here is a more complicated script file called blocks.py:...
Let’s look at an example of nestedifstatements with ourgrade.pyprogram. We can check for whether a grade is passing first (greater than or equal to 65%), then evaluate which letter grade the numerical grade should be equivalent to. If the grade is not passing, though, we do not need...

A nested loop is structurally similar tonestedifstatements Python for loop with range() function Python range is one of thebuilt-in functions. When you want the for loop to run for a specific number of times, or you need to specify a range of objects to print out, the range function wo...
We use try/except statements to provide exception handling. Now, the program tries to execute the division by zero. When the error occurs, our exception handling catches the error and prints a message to the screen. >>> try: ... print “[+] 1337/0 = “+str(1337/0) ... except:...
2while loopExecutes a block of statements repeatedly as long as the condition is TRUE. These two types of loops can be used inside each other to generatenested loops(more on this later). General Use Of Python Loops In Python, loops can be used to solve awesome and complex problems. You ...
Nested If You can haveifstatements insideifstatements, this is callednestedifstatements. Example x =41 ifx >10: print("Above ten,") ifx >20: print("and also above 20!") else: print("but not above 20.") Try it Yourself »
Logical operators often provide a way to simplify nested conditional statements. For example, we can rewrite the following code using a single conditional: if 0 < x: if x < 10: print('x is a positive single-digit number.') Theprintstatement is executed only when we pass both conditionals...
