What is format in Python?
In respect to this, what is %s and %D in Python?
%s is used as a placeholder for string values you want to inject into a formatted string. %d is used as a placeholder for numeric or decimal values. For example (for python 3) print ('%s is %d years old' % ('Joe', 42))
In this manner, what does %s mean in Python?
%s is a format specifier. The role of %s is that it tells the python interpreter about what format text it will be printing, on the console. String is the format in this case. So the syntax goes something like this.
In Python source code, an f-string is a literal string, prefixed with 'f', which contains expressions inside braces. The expressions are replaced with their values. The key point here is that an f-string is really an expression evaluated at run time, not a constant value.
