Trace the Code
x = 2
y = 9
print(x + y)
The variables x and y are added together. This results in the answer becoming 11.
for i in range(3):
print(i)
Answer:
0
1
2
Reason: The loop will run 3 times, this allows the values to print staring with the number 0 up to but not including the number 3
num = 3
if num == 5:
print”yes")
else:
print("no”)
The condition is false. This is ecause num is NOT equal to 5.
print("hello)
The string is missing a closing quotation mark which is why it won’t run, causing a syntax error.
What is a string?
A string is a sequenced closed with quotations, it is used to store text.
num = 3
if num % 2 == 0:
print(“even”)
else:
print(“odd”)
The number 7 is not divisible by the number 2. This means the elae will block the run.
x = 10
while x > 5:
x -= 2
print(x)
The loop will decrease by 1 until the sum is smaller than 5
score = 85
if score >= 90:
print("a")
elif score >= 80:
print("b")
else:
print("c")
The score is 85 which is less than 90. This means that the second condition is true because it is still a passing grade.
x = 3
if x > 5:
print("big")
if x > 2:
print("medium")
else:
print("small")
There is a missing elif for the if else statements. The else is only pared with the second if and not the first.
= vs. ==
= is used to assign a value to a variable
== is used to compare if to values are equal
def add(num):
num += 5
return num
x = 3
x = add(x)
print(x)
The function adds the number 5 to then return a new value that will infinite to chn he.
count = 0
for i in range(1, 10):
if i % 3 == 0:
count += 1
print(count)
In the loo the numbers may range from 1-10 but when ran it is excluded. The loop will count how many numbers are between 1 and 9 that are divisible by 3
x = 5
y = 10
if x > 3 or y < 5:
print("yes")
else:
print("no")
Yes, the condition is the because x is greater than 3 even when y isn’t less than 5.
for i in range(5):
print(i)
The print statement is not indented which is causing this indentation error.
Difference between for and while loop
For Loop: A For Loop is used to run a specific number of iterates over sequence
While Loop: A While Loop can run as long as its condition remains true
