1. Python – Input & Output

2. Output (to the terminal)
print(“Hello, world!”)
# What if we want to output multiple things?
print(“hello”, “world!”, 1, 2, 3)
# separate with commas

3. Input (via the terminal)
We will use the input() function: input(“prompt”)
line = input(“Please enter something:”)
print(line)
# line is a string

4. Input with numbers (incorrectly)
x = input(“Num 1:”)
y = input(“Num 2:”)
print(x+y)
# What do we see?

5. Input with numbers (correctly)
x = input(“Num 1:”)
x = int(x) #convert x to an int
y = int(input(“Num 2:”)) #we can also put it all in one line
print(x+y)
# What do we see?

6. Input with floats x = input(“Num 1:”)
x = float(x) #convert x to an float
y = float(input(“Num 2:”)) #we can also put it all in one line
print(x+y)
# What do we see?
