1.10 Indentations

• >Unlike using curly brackets in C/C++/Java for a code block, indentations are used in Python. Indentations can be of any range, usually four indentations are preferred, only constraint is that they should be consistent throughout that block of code. Any next un-indented line is used to show the end of that block of code.
• >They are used in Flow Control, Exception Handling, Functions/Classes definitions in Python, else IndentationError is raised. Every statement should follow the indentation rule.

## Example 1
# Notice: The colon at the end of 'if' condition,
# it is to show the start of block of code
if 10 > 5:
print('printed') # IndentationError


## Example 2
if 10 > 5:
  # preferred indentation
  print('printed')
print('block code ends')
# also valid indentation
if 10 > 5:
print('printed')
print('also printed')
# continue other code


## Example 3
class MyClass:
some_var = 10 # IndentationError
def my_function():
some_var1 = 20 # IndentationError
