Here is one that just removes parenthesis and their contents,uses all the capability.
text = "No parenth (alpha(how are you?) ((((add some)date),d) ending ) ) " # Sample
start = 0
end = start
size=len(text)
while start < size :
print(text)
end = text.find(')')
if end < 0 : break
start = text[0:end].rfind('(')
if start < 0 : break
text = text[0:start-1]+text[end+1:size-1]
size=len(text)
Learning about python, still. C coders will first just write python like it is c code, hen slowly begin to thumb through the documentation.
Just playing around with the various python features, I modify the parenthesis remover. I capture the parenthesis in a list, along with the character pointer, and I can replace them later.
text = "No parenth (alpha(how are you?) ((((add some)date),d) ending ) ) "
mylist=[]
def parenthesis(text) :
start = 0
end = start
size=len(text)
while True :
print(text)
end = text.find(')')
if end < 0 : break
start = text[0:end].rfind('(')
if start < 0 : break
mylist.append((start+1,text[start+1:end]))
text = text[0:start]+text[end+1:size]
size=len(text)
parenthesis(text)
for i in range(len(mylist)) : print(mylist[i])
So, I have the strings methods, list methods,and tuples, I think, let me look it up...yes, I did a tuple!
One morer! I want to collect the parenthesies from outer first to inner:
def outer_first(text) :
start = 0
end = start
size=len(text)
while True :
print(text)
end = text.rfind(')')
if end < 0 : break
start = text[0:end].find('(')
if start < 0 : break
mylist.append((start+1,end-start,text[start+1:end]))
text = text[start+1:end]
size=len(text)
And I learn clear(), keeps the list, just empties it.
