R1713 (consider-using-join)
Problematic code:
chars = ['H', 'e', 'l', 'l', 'o']
r = ''
for s in chars:
r += s
print(r)
Correct code:
chars = ['H', 'e', 'l', 'l', 'o']
print(''.join(chars))
Rationale:
Using str.join(sequence) is faster, uses less memory and increases
readability compared to for-loop iteration.
