Function in any programming language is a code that can be used over and over again easily. Functions are the most used part in all languages. Python function helps to make our code readable and short. We use def keyword for the function in python followed by the function name and semicolon ‘:‘ The syntax …
Python strings formatting is a way to modify the strings according to our needs. There are many different ways to format the strings. Python2 used a % operator to format a string whereas Python3 uses a new way of formatting using a string.format() method. Now, Python3.6+ even supports f-string.
Errors or Uncertainty in the measurement is the deviation of measured values from the exact (True) values. When we measure a physical quantity, there are many factors due to which we cannot get exact results. Such factors bring errors in our measurement.
Methods are the functions defined inside a class. Python string is also one of the predefined classes. Python string methods help to modify the string appearance and also can perform many other tasks.
Strings in Python is like a text that may contain an alphabet, numerical value, space as well as special characters. The only condition is: those characters should be enclosed by a single or double quote.
Significant figures can be defined as digits in a number that is necessary to indicate the reliable value of measurement. Reliable means those values that are within the measurement resolution or capacity.

Dimensions are the power to which the fundamental quantity is raised to represent any physical quantity. The dimension and unit of seven fundamental quantities can be written as:
The process of splitting vectors into many components is called the resolution of vectors. It is also known as a splitting of vectors. Think of it as distributing vector total effect into smaller parts.
When an object is thrown with a certain initial velocity and that moves under the effect of gravity alone, we say that object is a projectile and the motion is projectile motion. The path of that motion is called a trajectory.
