In Python programming, precision and reliability are necessary. The “assert” statement makes sure safeguards the code against errors and anomalies. It is a sentinel of truth, a guardian of code correctness, and an invaluable ally in the pursuit of bug-free code. Advertisements The “assert” ...
In such cases, we can use the % operator to specify the format of the strings in python. The syntax for specifying the format is as follows. 1 2 3 %[width][.precision]type Here, width is the total length the value from the variable can take. precision is the number of digits ...

A new class of time functions in Python 3.7 return time values with nanosecond precision. Even though Python is an interpreted language, Python core developer Victor Stinner made a case for reporting time with nanosecond accuracy. The biggest reason is to avoid losing precision when dealing with ...
