for loop is not block!

In this video, you have said that for loop is a block, and in Python for Beginners section of Python Basics course in video Syntax and Style you said that block is what is beneath(and indented) for loop or function. What is block?

A block(also known as code block) is a section of code grouped together. In Python a block is indicated by indention.

# This is a code block
if True:
    # statement here
    # another statement

# This is a code block
for x in range(10):
    # statement here
    # another statement

# This is a code block
while True:
    # statement here
    # do something
# statement here, but is not part of code block since it is unintended

You can also have a block with a block.
