FOR Loop

For Loop
A for loop is a repetition control structure that allows you to efficiently write a loop that needs to be executed a specific number of times.
A for loop is useful when you know how many times a task is to be repeated.
Syntax : 
for(initialization; Boolean_expression; update) {
   // Statements
}
This is how it works : 

The initialization step is executed first, and only once. This step allows you to declare and initialize any loop control variables and this step ends with a semi colon (;).
Next, the Boolean expression is evaluated.  If it is true, the body of the loop is executed. If it is false, the body of the loop will not be executed and control jumps to the next statement past the for loop.
After the body of the for loop gets executed, the control jumps back up to the update statement. This statement allows you to update any loop control variables. This statement can be left blank with a semicolon at the end.
The Boolean expression is now evaluated again. If it is true, the loop executes and the process repeats (body of loop, then update step, then Boolean expression).  After the Boolean expression is false, the for loop terminates.

For loop

for( initialize; test; increment or decrement)

{

//code;

//code;

}

for loop

const n = 7; 

for(let i = 0; i <= n; i++) console.log(i);

// output -> 0, 1, 2, 3, 4, 5, 6, 7 

for loop

newlist = []

for word in wordlist:
    newlist.append(word.upper())

for loop

for i in 0..5 {
    println!("{}", i * 2);
}

for i in std::iter::repeat(5) {
    println!("turns out {} never stops being 5", i);
    break; // would loop forever otherwise
}

'outer: for x in 5..50 {
    for y in 0..10 {
        if x == y {
            break 'outer;
        }
    }
}

what are for loops

# There are 2 types of loops in python
# while loops and for loops
# a while loops continues for an indefinite amount of time
# until a condition is met:

x = 0
y = 3
while x < y:
    print(x)
    x = x + 1

>>> 0
>>> 1
>>> 2

# The number of iterations (loops) that the while loop above
# performs is dependent on the value of y and can therefore change

######################################################################

# below is the equivalent for loop:
for i in range(0, 3):
    print(i)

>>> 0
>>> 1
>>> 2

# The for loop above is a definite loop which means that it will always
# loop three times (because of the range I have set)
# notice that the loop begins at 0 and goes up to one less than 3.

for loop

a=5
b=2
for a > b:
a+=1
pint(a)

for loop

newlist = []

for word in wordlist:
    newlist.append(word.upper())
    
# instead, use this:

newlist = map(str.upper, wordlist)

for loop
