How to find the last line number of a section in a text file (particular format)
I'm writing a function which reads specified sections in a text file formatted a particular way, but I'm having a hard time figuring out how to locate the last line number. Here's an example of the text file's format, where the numbers correspond to unique sections contained within the square brackets:
[1
Some text
]
[8
Some text
Some text
]
And here's the relevant parts of my code so far:
def readSection(sectionNumber):
fileLines = open(file).readlines()
for lineNumber, line in enumerate(fileLines, 1):
start = '[' + str(sectionNumber)
if start in line:
firstLineNumber = str(lineNumber)
Expected output based on format example: if sectionNumber is 1, firstLineNumber is 1 and lastLineNumber is 3. If sectionNumber is 8, firstLineNumber is 5 and lastLineNumber is 9.
Assigning the variable end to ']' gets the line number of every closing bracket, so I need a way to only get the first one after firstLineNumber but Google hasn't given me any useful information.
