Trace the Code
x=3
x=x+2
print(x)
The answer is 5
The x is starting at 3 but then it goes to add 2 to it making the output to 5
How many times does “hi” print?
for i in range (3):
Print(“hi”)
3
The loop is going to run one time for each number in the range 3 which will have the output to 3
If it is raining, you bring an umbrella. Otherwise, you wear sunglasses.
It is raining. What should you do?
Bring an umbrella
Since it is raining, the if condition is true, so you should bring an umbrella.
what is wrong with the logic code
for i in range (1,5):
Print(i)
The loop does not include 5
the programmer is going to think range (1,5) goes up to the number 5 but it stops before the second number
What is a variable
A place to store a value
It’s going to hold information so the program can use it later
X=10
y=x-4
x=y+1
print(x)
the answer is 7
:
The y is going to become 6 then the x is going to reassigned to y +1 which then would equal to 7
What is printed?
total=0
for i in range (4):
Total += i
print(total)
6
The loop will add 0,1,2 and then the total to 3 making the result 6
If your homework is finished, you can play video games. Otherwise, you must keep working.
Your homework is not finished. What should you do?
Keep working.
The if condition is false, so the else action happens
What is wrong with this logic code
x=0
while x<5:
Print(x)
What's wrong is that the loop is not going to stop
The value x is never going to change, so the condition remains true forever, causing the loop to continue indefinitely.
What does a loop do
It repeats the code
Loop run the same code multiple time without rewriting it
a=5
b=a
a=a+3
print(b)
5
The b from the value of a is going to change not now but after then it will not change
Count =0
for i in range(1,6):
If i % 2 == 0:
Count +=1
print(count)
2
Only even numbers 2 and the 4 will rise the count so its then increments twiceL
What is printed?
X =8
if x % 2==0:
If x >10:
Print(“big even”)
Else:
Print(“small”)
else:
Print(“odd:)
The answer is small even
Explanation:
The x is the even but it not greater than 10 so the inner else runs
What's wrong with the loop
score=85
if score >90:
Prints(“A”)
if score >80:
Print(“b)
More than one grade can be printed
If you're using two separate if statements, it allows it to multiply the condition to run when only one outcome should occur.
Difference between = and ==
= it sets the values ==it going to compare the values
One assigns data to the variable while the other one checks if two values are the same or equal.
