Python Lessons – 1.5 Strings
In Python You can use text and you can do it using strings, or strings. You can define a string using both the single and the double quotation mark.
Python Lessons – 1.6 Input and Output
Often when running a program, you must return some text strings (output) to the console. We have already seen that to correctly report a string or variable you use the function print ().
Python Lessons – 1.7 Operations on Strings
Perhaps the most used operation on strings is the concatenation of two or more strings. That is, it is often necessary to combine more strings to form longer sentences.
Python Lessons – 1.8 Type conversion
It often happens (even much more than we realize) that in the lines of code to perform operations between values of different types. We've already seen it between integers and floats. In fact, the integers were implicitly converted to float by the interpreter and then the operation was performed. In This case we talk about implicit conversions.
Python Lessons – 1.9 Variables
The variables are practically indispensable in programming and serve to store values in order to be used later.
Python Lessons – 1.10 In-Place Operators
There are some operators that allow you to write numeric expressions in a more contracted form using with only one operator both the operation and the assignment.
Python Lessons – 1.11 Using an editor
An IDLE is a text editor that allows you to do the programming, that is the writing of the programs in Python in a simple and fast. In fact from the same editor, you can create a new. py file, write the code, run the program, fix the errors, and save the program, to reuse it at a later time
Python Lessons – 2.11 FOR Loop
Each element of the list array is copied into a temporary variable called item, on which you will work within the for loop by writing a series of commands in the indentation. No need for counters, no need to know how long the list is.
Python Lessons – 2.1 Flow control
In programming the ability to have these values allows us to manage in a very simple way some operations like for example the conditions. [
Python Lessons – 2.2 The conditional construct IF
The IF command is used to construct conditional constructs. The IF construct consists of a condition and a set of instructions within it. If the condition produces a True value, that is, the statements within the construct are verified, otherwise no and execution passes to the next command
