'Too many statements (%s/%s)'
Used when a function or method has too many statements. You should then split it in smaller functions / methods.
For the example, pylint was configured to accept at max five statements (default is 100).
def fn(): a = 1 b = 2 c = 3 d = a * b + c print(d)
1:0: R0915: Too many statements (6/5)
Functions and methods with too many statements are hard to understand.
