loops in python
#While Loop:
while ("condition that if true the loop continues"):
#Do whatever you want here
else: #If the while loop reaches the end do the things inside here
#Do whatever you want here
#For Loop:
for x in range("how many times you want to run"):
#Do whatever you want herefor loop
// this is javascript, but can be used in any language
// with minor modifications of variable definitions
let array = ["foo", "bar"]
let low = 0; // the index to start at
let high = array.length; // can also be a number
/* high can be a direct access too
the first part will be executed when the loop starts
for the first time
the second part ("i < high") is the condition
for it to loop over again.
the third part will be executen every time the code
block in the loop is closed.
*/
for(let i = low; i < high; i++) {
// the variable i is the index, which is
// the amount of times the loop has looped already
console.log(i);
console.log(array[i]);
} // i will be incremented when this is hit.
// output:
/*
0
foo
1
bar
*/For loop
for( initialize; test; increment or decrement)
{
//code;
//code;
}for loop
for (let i = 0; i < substr.length; ++i) {
// do something with `substr[i]`
}for loops
for (initialization expr; test expr; update expr)
{
// body of the loop
// statements we want to execute
}
**Initialization Expression: In this expression we have to initialize the loop counter to some value. for example: int i=1;
Test Expression: In this expression we have to test the condition. If the condition evaluates to true then we will execute the body of loop and go to update expression otherwise we will exit from the for loop. For example: i <= 10;
Update Expression: After executing loop body this expression increments/decrements the loop variable by some value. for example: i++;**Copyright © 2021 Codeinu
