How to append the data from a text file to a list only from a given starting point rather then appending full file using python

Question

I want to append data from text file to a list from a given starting point. The stating point string can be anywhere in the file. i want to append the data from that starting point. I tried by using startswith method:

list1=[] 
TextFile = "txtfile.txt"
# open the file for data processing
with open(TextFile,'rt',encoding="utf8") as IpFile:
    for i,j in enumerate(IpFile):
        if(j.startswith("Starting point")):
            list1.append(str(j).strip()) 
            i+=1      

but it only append the starting point. i want to append the all data from starting point. How to do that ?

Use a boolean variable

list1=[] 
TextFile = "txtfile.txt"
doAppend = False
# open the file for data processing
with open(TextFile,'rt',encoding="utf8") as IpFile:
    for i,j in enumerate(IpFile):
        if(j.startswith("Starting point")):
            doAppend = True
        if doAppend:
            list1.append(str(j).strip()) 
            i+=1
