Is there a shorthand in Python for (e.g.) print(f'type(var) = {type(var)}')
, without having to state the object in the text and the {.}
?
The short answer may be "no", but I had to ask!
E.g. in SAS one may use &=
to output a macro variable and its value to the log...
%let macrovar = foobar;
%put &=macrovar;
which returns in the log: MACROVAR = foobar
This is my first question, and I found it difficult to search for an answer, so apologies if it's been asked and answered.
Python print() Function The print() function prints the specified message to the screen, or other standard output device. The message can be a string, or any other object, the object will be converted into a string before written to the screen.
How to Print the Type of a Variable in Python. To get the type of a variable in Python, you can use the built-in type() function. In Python, everything is an object. So, when you use the type() function to print the type of the value stored in a variable to the console, it returns the class type of the object.
Answer. In Python, string formatters are essentially placeholders that let us pass in different values into some formatted string. The %d formatter is used to input decimal values, or whole numbers. If you provide a float value, it will convert it to a whole number, by truncating the values after the decimal point.
Using f-strings in Python to print variables is the most commonly used method and I would personally recommend using this method. In this method, an 'f' is placed before the opening quotation mark of a string. Braces {} are placed around the names of variables that you are looking to print.
Indeed there is. As of python 3.8, you can simply type f'{type(var)=}'
, and you will get the output you desire:
>>> x = {}
>>> f'{x=}'
'x={}'
>>> f'{type(x)=}'
"type(x)=<class 'dict'>"
