fr Peter:

# in Python this function is ‘’.zfill(5)

# another possibility would be 5\*‘0’

# 

# Equivalents in Ruby? I would be mainly interested in a zfill

# equivalent

# since that is faster that join or 5\* imho.

same here.

irb(main):043:0\> ‘0’\*5  
=\> “00000”  
irb(main):044:0\> ‘0’\*3  
=\> “000”
