### Root systems algorithm: "TypeError: 'str' object is not callable"

I am rather new to SAGE and formal language. I am running the following code which works fine with a slighty simpler version (where the variables p1,p2,...p5 in the function letsapply are fixed): Here is the original function that works fine:

def letsapply(listg, alist):
mylistg = listg
mylistg.reverse()
for si in mylistg:
if si == 's1':
alist = map(s1, alist)
elif si == 's2':
alist = map(s2, alist)
elif si == 's3':
alist = map(s3, alist)
elif si == 's4':
alist = map(s4, alist)
elif si == 's5':
alist = map(s5, alist)
elif si == 's6':
