It’s used to get the remainder of a division problem. The modulo operator is considered an arithmetic operation, along with + , – , / , * , ** , // .

What does F mean in Python?

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.

What is G in Python?

What does * mean in Python?

The asterisk (star) operator is used in Python with more than one meaning attached to it. For numeric data types, * is used as multiplication operator >>> a=10;b=20 >>> a*b 200 >>> a=1.5; b=2.5; >>> a*b 3.75 >>> a=2+3j; b=3+2j >>> a*b 13j.

What does AB mean in Python?

Can we use %d in Python?

Python uses C-style string formatting to create new, formatted strings. The “%” operator is used to format a set of variables enclosed in a “tuple” (a fixed size list), together with a format string, which contains normal text together with “argument specifiers”, special symbols like “%s” and “%d”.

What does %f mean Python?

F-strings provide a way to embed expressions inside string literals, using a minimal syntax. It should be noted that an f-string is really an expression evaluated at run time, not a constant value. In Python source code, an f-string is a literal string, prefixed with ‘f’, which contains expressions inside braces.

What is printf Python?

In Python, there is no printf() function but the functionality of the ancient printf is contained in Python. To this purpose, the modulo operator % is overloaded by the string class to perform string formatting. Therefore, it is often called a string modulo (or sometimes even called modulus) operator.
