-----------------------------------------------
finds = ("{", "}", "(", ")")
lines = file("foo.txt", "r").readlines()
for line in lines:
for find in finds:
if find in line:
line.replace(find, "")
print lines
-----------------------------------------------
I want something like
-----------------------------------------------
finds = file("replace.txt")
lines = file("foo.txt", "r").readlines()
for line in lines:
for find in finds:
if find in line:
line.replace(find, "")
print lines
