python - Cut off string after a certain length -

i wrote code:

name = 'programmstrukturen 2' num1=5 num2='$' lang_name=len(name)  m_res=lang_name % num1  x in range(num1):     print 'x =' + str(x)     print 'num1='+str(x)     print name[x] + name[x+num1] + name[x+num1+num1] + name[x+num1+num1+num1] 

what pretty easy, prints i+4 + i+4+4 + i+4+4+4 chars amount of num1. working , there chance improve loop reducing last line ? , put outputs one?

current output:

x =0 num1 =0 parr x =1 num1 =1 rmue x =2 num1 =2 omkn x =3 num1 =3 gst x =4 num1 =4 rtu2 

wished output:

parrrmueomkngst rtu2 

can done += or .join ?

name = 'programmstrukturen 2' num1=5 output='' x in range(num1):     in range(num1-1):         output+=name[x+num1*i]    #you simplify long line  print output

>>>  parrrmueomkngst rtu2
