Isn't the length going to be 10 instead of 11

How can len function is giving 11 output your name is of 10 string character

thanku so much sir for effort without any expecting anything….

Really looks simple when you explain things. Since coming from a non-coding background, this teaching technique method is really easy to understand.

>>> print ('Thanks Navin')

Print like This ######### Telusko n Rocks

used the underscore and a number i got the error below.
print (_+ 2)

TypeError Traceback (most recent call last)

Input In [18], in <cell line: 1>()

—-> 1 print (_+ 2)

TypeError: can only concatenate str (not "int") to str

Super. You made session as more info with simple.

Same as it is because here r represents raw string which give same string.

Variables

Variables are containers for storing data values.

Creating Variables

Python has no command for declaring a variable.

A variable is created the moment you first assign a value to it.

Variables do not need to be declared with any particular type, and can even change type after they have been set.

x = 5

y = "John"

print(x)

print(y)

Output : 5 john

Casting

If you want to specify the data type of a variable, this can be done with casting.

x=str(3)

y=int(3)

z=float(3)

​

print(x)

print(y)

print(z)

​

Output:

3

3

3.0

Get the Type

You can get the data type of a variable with the type() function.

x = 5

y = "John"

print(type(x))

print(type(y))

Output :

<class 'int'>

<class 'str'>

Single or Double Quotes?

String variables can be declared either by using single or double quotes:

x = "John"

print(x)

#double quotes are the same as single quotes:

x = 'John'

print(x)

Case-Sensitive

Variable names are case-sensitive.

a = 4

A = "Sally"

#A will not overwrite

Python – Variable Names

Variable Names

A variable can have a short name (like x and y) or a more descriptive name (age, carname, total_volume). Rules for Python variables:

• A variable name must start with a letter or the underscore character

• A variable name cannot start with a number

• A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ )

• Variable names are case-sensitive (age, Age and AGE are three different variables)

Legal variable names:

myvar = "John"

my_var = "John"

_my_var = "John"

myVar = "John"

MYVAR = "John"

myvar2 = "John"

Illegal variable names:
2myvar = "John"

my-var = "John"

my var = "John"

Remember that variable names are case-sensitive

Multi Words Variable Names

Variable names with more than one word can be difficult to read.

There are several techniques you can use to make them more readable:

Camel Case

Each word, except the first, starts with a capital letter:

myVariableName = "John"

Pascal Case

Each word starts with a capital letter:

MyVariableName = "John"

Snake Case

Each word is separated by an underscore character:

my_variable_name = "John"
