Python-specific rules:

• SIM101 ("Multiple isinstance-calls which can be merged into a single call by using a tuple as a second argument")
• SIM105 ("Use 'contextlib.suppress(...)' instead of try-except-pass")
• SIM107 ("Don't use return in try/except and finally ")
• SIM108 ("Use the ternary operator if it's reasonable ")
• SIM109 ("Use a tuple to compare a value against multiple values")
• SIM110 ("Use any(...) ")
• SIM111 ("Use all(...)")
• SIM113 ("Use enumerate instead of manually incrementing a counter")
• SIM114 ("Combine conditions via a logical or to prevent duplicating code")
• SIM115 ("Use context handler for opening files")
• SIM116 ("Use a dictionary instead of many if/else equality checks")
• SIM117 ("Merge with-statements that use the same scope")

Simplifying Comparisons:

• SIM201 ("Use 'a != b' instead of 'not a == b'")
• SIM202 ("Use 'a == b' instead of 'not a != b'")
• SIM203 ("Use 'a not in b' instead of 'not (a in b)'")
• SIM208 ("Use 'a' instead of 'not (not a)'")
• SIM210 ("Use 'bool(a)' instead of 'True if a else False'")
• SIM211 ("Use 'not a' instead of 'False if a else True'")
• SIM212 ("Use 'a if a else b' instead of 'b if not a else a'")
• SIM220 ("Use 'False' instead of 'a and not a'")
• SIM221 ("Use 'True' instead of 'a or not a'")
• SIM222 ("Use 'True' instead of '... or True'")
• SIM223 ("Use 'False' instead of '... and False'")
• SIM300 ("Use 'age == 42' instead of '42 == age'")

Simplifying usage of dictionaries:

• SIM401 ("Use 'a_dict.get(key, "default_value")' instead of an if-block")
• SIM118 ("Use 'key in dict' instead of 'key in dict.keys()'")

General Code Style:

• SIM102 ("Use a single if-statement instead of nested if-statements")
• SIM103 ("Return the boolean condition directly")
• SIM112 ("Use CAPITAL environment variables")
