How the input function works in Python :

The Input is nothing but some value from a system or user.

When input() function executes program flow will be stopped until the user has given an input.

input(): Whatever you enter as input, input function convert it into a string. If you enter an integer value still input() function convert it into a string. You need to explicitly convert it into an integer in your code using typecasting.

• Use the prompt parameter to write a message before the input(‚Give me the first number: ‚)

In most cases, the corresponding cast-operator is immediately applied to the result string of input in order to obtain the data type required (like integer, float etc.) for further processing:

age = int(input(‚Your age: ‚))

… sounds boring, is boring – but even though it is important to know them.

Variables reserve memory locations to store values depending on data type:

Numerical types:

• int (signed integers)
• long (long integers, they can also be represented in octal and hexadecimal)
• float (floating point real values)
• complex (complex numbers)

Strings str are mostly used for saving word, sentences or texts. Subsets of strings can be taken using the slice operator ([ ]) (indexes starting at 0, ending at string length -1)

Boolean values bool can be true or false and are used in Logical operations.

There are many more data types in Python but for the time the mentioned are sufficient.

As you can see:

• Comments don’t suck, they help understanding your code
• KEEP IT SIMPLE, because simple is better than complex

… no they don’t!

It is important to use comments that your codes can easily understood by others:

1. Giving variables ovious names
2. # Python ignores everything after the hashtag up to the end of the line
3. Multiline comments are mostly used for documentation

But: Keep it simple!

First assignment was to perform simple arithmetic operations.

To be aware of:

• Integer ≠ String
• x % y Modulo Operator
• x/y Divisor can be float value
• x//y Divisor is only integer value
