In the previous activity, the math expressions were output seperately from the strings. Although this works, it doesn’t look nice. In programming we format strings to construct complex text messages. In Python, there are two popular ways to format strings: passing multiple arguments* and string interpolation.
Passing multiple argument simply means you separate the different data in the print function with commas.
print("My age in months is ", 30 * 12)
* If we’re arguing semantics, this is technically output formatting, not string formatting, but it has the desired effect.
A newer way to format strings is to use a feature called string interpolation. With string interpolation, you prefix a string with the character f. You then use the {} symbol to insert code expressions anywhere you want execute code in the string.
f"My age in months is {30 * 12}."
print() function# Passing multiple arguments - Use the *,* character to seperate data that you want to put together.
print("10 squared is ", 10 * 10)
print()
# You can use parentheses to ensure the addition is not mixed up with concatenation.
print("I'm 5 foot 10 inches. That's ", 5 * 12 + 10, " inches.")
print()
# String inpterpolation - Prefix the string with an f and insert code within { }.
print(f"If I take out a $1000 loan, and pay $25 each month, I will pay my loan off in {1000 / 25} months.")
print()
print("A woodchuck can chuck 32 wood panels every minute.")
print(f"Therefore, a woodchuck can chuck {32 * 60} wood panels every hour.")
print()
10 squared is 100
I'm 5 foot 10 inches. That's 70 inches.
If I take out a $1000 loan, and pay $25 each month, I will pay my loan off in 40.0 months.
A woodchuck can chuck 32 wood panels every minute.
Therefore, a woodchuck can chuck 1920 wood panels every hour.
