I am trying fix some indentation errors in a Python script. Is there a way to auto correct the errors online or using other utilities?
I hope this error is very familiar, but wanted to avoid this again. Does any editor help in fixing these issues?
IndentationError: expected an indented block
It's not possible in general because some cases would be ambiguous:
something = foo()
if something:
something.bar()
print("ok") # Only half indented. Should this be inside or outside of the if statement?
It's much better to find an editor with auto-indentation support and make sure you indent properly (even in languages without significant whitespaces, as it makes your code easier to read).
You can use reindent.py.
For me, it worked on some files, but it didn't work on others. Give it a try.
Usage:
reindent.py <filename>.py
Change Python (.py) files to use 4-space indents and no hard tab characters.
Also trim excess spaces and tabs from ends of lines, and remove empty lines at the end of files.
You can use Spyder IDE
Source Menu -> Fix Indentation
This particular error usually occurs when you forget to add an indented block after a statement that needs one (i.e. if or for). You likely forgot to indent the required block or accidentally hit backspace (or something) such as
def sayhello():
print "Hello world!"
Sometimes you don't want any code after an if statement or after try/except statements, but python will require at least one line after them, so you can use the pass keyword
try:
x= 4/0
except:
pass
print x
