The timeit module lets you measure the execution time of small bits of Python code

import timeit
timeit.timeit('"-".join(str(n) for n in range(100))',
                  number=10000)

# 0.3412662749997253

timeit.timeit('"-".join([str(n) for n in range(100)])',
                  number=10000)

# 0.2996307989997149

timeit.timeit('"-".join(map(str, range(100)))',
                  number=10000)
