I don't really understand 'if-statements' can someone please help me find a way to make it easier for me to learn?

Answer 1

Thats cool, I like Python

Anyway, here's the explanation:

An if statement is a "decision-making" statement. It checks to see if an expression evaluates to "True". For example, "4 > 3" will be True because 4 is greater than 3

If the expression in the if-statements definition evaluates to True, the if-statement's code block will be run. Otherwise, the interpreter will skip over the if-statement until the expression eventually evaluates to True

The definition of an if-statement is as follows:

if #condition#:
code to run if condition is True

For example:

x = int(input())
if x > 0:
print("Input is greater than 0")

Thats how easy it is😁. Follow-up comments incoming on elif and else statements

Answer 2

In which language?

Answer 3

in Python. Sorry for not clarifying before

Answer 4

thank you so much! it really helped!

Answer 5

As we saw in the first comment, when an if-statement's expression evaluates to False, the interpreter will skip over it. But what if you want something to happen if the expression is False🤔

This is where the elif and else statements come in

The else statement holds code that will be run if the if-statement preceeding it has an expression Evaluating to False.

For example:

x = int(input())
if x > 0:
print("Number is positive")

else:
print("Number is negative")

The next statement is called elif. This is short for "else if". This statement denotes additional decision making if preceeding if- and elif-statements evaluate to False.

For Example:

age = int(input())
if age < 0:
print("You cant be less than 0 years old")

elif age == 0:
print("Happy Birthday!")

elif age >= 18:
print("You are an adult")

else:
print("You are a child")

As you can see, multiple elif-statements can be chained together for more complex decisions

This concludes the short tutorial I guess😅
