F String With Special Characters

Question

I want to print the following using an f string literal. It will be running wihtin a function and apples will be one of the arguments. I want it to have the square brackets included.

"I like [apples] because they are green"

I have tried the following code:

"I like {} because they are green".format("apples")

The code above prints:

I like apples because they are green

How do I insert the square brackets [ ] or another special character such as < > into the f string literal?

Answer 1

There are a couple possible ways to do this:

"I like [{}] because they are green".format("apples") or "I like {} because they are green".format("[apples]").

If instead of brackets you wanted to use actual special characters, you would just have to escape in the appropriate place:

"I like {} because they are green".format("\"apples\"").

Additionally, if you wanted to use actual f-strings, you could do the same thing as above but with the format:

f"I like {'[apples]'} because they are green"

but make sure to switch from double quotes to single quotes inside the brackets to avoid causing troubles by ending your string early.

Answer 2

Here are few suggestions on how to use special characters in f-string.

1. If you want to print

Hello "world", how are you

var1 = "world"
print(f"Hello \"{var1}\", how are you") 

2. To print:

Hello {world}, how are you

where world is a variable

var1 = world 
print(f"Hello {{var1}}, how are you")

3. To print:

Hello {world}, how are you

where world is a constant

print(f"Hello ""{world""}, how are you")

Answer 3

To print: Hello {world}, how are you

where world is a variable

var1 = world 
print(f"Hello {{var1}}, how are you")

is not correct. You have to add one extra bracket

var1 = world 
print(f"Hello {{{var1}}}, how are you")

since in f-string double brackets plots a single bracket
