Using an F-string

I guess %s operator is in Python from python 2.0 and some were habitual to it so he tells about that while F-string introduced in python 3.6.
F-string easy to use and quite readable but its personal preference which one to use

https://realpython.com/python-f-strings/ shows how the old way of formatting strings can quickly become hard to read.

Hi everyone!
Thanks for reaching out.

The release of Python version 3.6 introduced formatted string literals, simply called “f-strings.” They are called f-strings because you need to prefix a string with the letter 'f' to create an f- string. The letter 'f' also indicates that these strings are used for formatting. Could you please share with us your code as a post? Thank you.

Looking forward to your answer.

product_category = [500, 600]

# The string interpolation operator (%), or modulo operator:

print("We currently have %d available units of this item." % product_category[0])

# Same can be achieved with the f-string formatting:
print(f"We currently have {product_category[0]} available units of this item.")

stock_share_price_list = [40.50, 60.35]

# The string interpolation operator (%), or modulo operator:
print("This stock costs $%.2f per share." % stock_share_price_list[0])

# f-string formatting:

print(f"This stock costs ${stock_share_price_list[0]:.2f} per share.")
