I am getting error while running this code. What’s the issue?

line1 = “I love you”
line2 = “I miss you”
print(line1\n\line2)

I tried mixing variable and line break.

Keep in mind that \n is an escape character and must go between quotes, think of it as a word. You can try something like:

print(line1 + "\n" + line2)

In same line.

I formulated this, still has error.

We’ve defined the variable “meal” here to the name of the food we ate for breakfast!

meal = “An english muffin”

Printing out breakfast

print(“Breakfast:”)

print(meal)

Now update meal to be lunch!

meal = “A big sandwich”

Printing out lunch

print(“Lunch:”)

print(meal)

Now update “meal” to be dinner

meal = “lasagna”

Printing out dinner

print(“Dinner:”)

print(meal)

I have a few questions concerning Variables:

  • First of all, will a string always be a variable as long as I use the format (where “string” can be anything that doesn’t start with a number and only has underscores “_” or numbers within it)

string = “example”

  • Second, if I am using the same variable name multiple times, will the variables associated data (block of texts or anything else) always be the one associated to the latest one?

For example, for the following code:

meal = “omelette”
print(“Breakfast:”)
print(meal)
print(“Brunch:”)
print(meal)

print(meal) would always print the latest precision for meal, right? (In this case, omelette)

If I were to include another designation for meal, the latest one would override the initial one?

In this case:

meal = “omelette”
print(“Breakfast:”)
print(meal)
meal = “hashbrown”
print(“Brunch:”)
print(meal)

According to what I understand, print(meal) would display “omelette” first instance, and then display “hashbrown” for the second instance. Am I correct on this point?

Thus, if I want to have the initial designation, I would have to write another line of

meal = “omelette”

So that for subsequent print(meal), I should be able to only print “omelette” instead of “hashbrown”?

Thank you in advance for your answers!

Hey , that’s a pretty good question, in order to do that you have to print the message in the same line so,
print("dinner: " + meal)

so instead of printing dinner and meal alone , we combine them with a “+”
