Can you do nested for loops in Python?

Can you do nested for loops in Python?

Nested For Loops Loops can be nested in Python, as they can with other programming languages. The program first encounters the outer loop, executing its first iteration. This first iteration triggers the inner, nested loop, which then runs to completion.

How do I run two for loops in JavaScript?

Yes you can do a for loop like that, but you have one and just one condition for check.

JavaScript for loop

1. The initialExpression initializes and/or declares variables and executes only once.

3. The updateExpression updates the value of initialExpression when the condition is true .
4. The condition is evaluated again.

How do you write nested if statements in JavaScript?

The way the logic works here is:

1. If the first condition is true ( if (a == b) ), then the program checks for the nested if condition ( if (a == c) ).
2. If the nested if is true, the statement is executed, i.e. “all are equal”.
3. If the nested if is false, then the else statement is executed, i.e. “a and b are equal”.
