Indentation Error

Question

I keep getting told about an indentation error. As far as I know this series isn't explicit about how to use indentations. It's quite frustrating. I'm left to guess and try and keep getting told the same error.

Hi Gary. In python, indentation is used to start and end code blocks (by this i mean for loops, while loops, conditional statements etc). When you start a block of code, you use indentation to signify that this code belongs to this block. To end a code block, you dedent. Usually, you would indent by 4 spaces or you can just press the tab key. Any lines that are indented at the same level belong to that block of code. An example of this would be:
```python
for i in range(10):
    print("Hello") #this code is indented and therefore belongs to the for loop.
                   #this will happen 10 times
```
If you wish to exit this block of code, you go back to writing with no indentation:
```python
for i in range(10):
    print('Hello') #this code is indented and therefore belongs to the for loop.
print('bye') #this will only be printed once as it is not part of the block of code above
```
The same principal goes for defining functions, conditional statements, loops etc.
