String interpolation in python.

Feb 28, 2022 · Here, we’ve constructed a new string with `%s`python replaced by `name`python and %d replaced by age. In addition to knowing the format specifiers, we’ll want to learn the syntax. In particular, our template string is following by the modulo operator. Of course, in this context, we can call it the string formatting or interpolation operator.

1 Answer. Sorted by: 13. I think that numpy.interp is exactly what you want. e.g.: numpy.interp(value_x,array_x,array_y) Note that here value_x can be a scalar or another array-like value.

In Python 3.6+ you can use much more convenient and efficient f-strings for interpolation, e.g: f'{val1} {val2} {val3}' where replacement fields are expressions evaluated at run time.

💡 Problem Formulation: String interpolation refers to the insertion of a variable’s value directly into a string.
