Description
The use of operators pairs ( =+ or =-) where the reversed, single operator was meant (+= or -=) will run fine, but not produce the expected results.
This rule raises an issue when =+ or =- is used without any spacing between the two operators and when there is at least one whitespace character after.
Noncompliant Code Example
target = -5 num = 3 target =- num # Noncompliant; target = -3. Is that really what's meant? target =+ num # Noncompliant; target = 3
Compliant Solution
target = -5 num = 3 target = -num # Compliant; intent to assign inverse value of num is clear target += num
