import math
def example1():
some_tuple = (1, 2, 3, 'a')
some_variable = {
'long': 'Long code lines should be wrapped within 79 characters.',
'other': [, 100, 200, 300, 9876543210,'This is a long string that goes on'],
'more': { 'inner': 'This whole logical line should be wrapped.',some_tuple: [ 1,20, 300, 40000,500000000,60000000000000000]}}
return (some_tuple, some_variable)
def example2(): return ('' in {'f': 2}) in {'has_key() is deprecated': True};
class Example3(object):
def __init__(self, bar):
# Comments should have a space after the hash.
if bar:
bar += 1
bar = bar * bar
else:
some_string = """
Indentation in multiline strings should not be actual code should be reindented.
"""
The first way:
After writing the code, right click and select "Extern Tools" - > "autopep8"
The second way:
Select "Tool" - > "Extern Tools" - > "autopep8" in the menu.
