Nested Loop lines in a file n times (Example 3) below: Python

Question

I have a file with lines which need to be repeated as many times as the decimal/hex value mentioned in the first line.

Input Example:

Loop  3  {Line1}  ##the line is within curly braces so I used regex but not printing it out right. 
Label: Blank {Line2}
Jump Label {Line3} 

Output Example:

Line1
Line2
Line3
Line2
Line3
Line2
Line3

My code so far:

line_1_ = re.compile(r'Loop\s*([0-9]+|0x[0-9a-fA-F]+)\s*\{(\w+)\}', re.DOTALL)
for match in line_1_.finditer(inputfileContents):
    looptimes =  int(match.group(1))
    line_1 = match.group(2)
    jump = re.search(r'Jump\s*(\w+)\s*\{(.*?)\}', inputfileContents, re.DOTALL)
    label = re.search(r'(\w+):\s*(\w+)\s*\{(\w+)\}', inputfileContents, re.DOTALL)
    for i in range(looptimes):
        if jump.group(1) == label.group(1):
            print '%s\n%s' % (label.group(3), jump.group(2))

Error: I cannot increment a line with line++. Which I understand as it is a string but not sure how to increment it otherwise.

Effectively it is just repeating Line2 and Line 3 3 times. But if there are multiple lines between the Jump and loop it has to print all the lines starting from Label statement to the jump statement including the jump statement.

This doesn't work if there are multiple lines between the jump and label statements...

Example 2:

Blank {Line0}
Loop  3  {Line1}  
Label: Blank {Line2}
       Blank {Line3}
       Blank {Line4}
Jump Label {Line5}
Blank {Line6}

Expected Output int he above case:

Line0
Line1
Line2
Line3
Line4
Line5
Line2
Line3
Line4
Line5
Line2
Line3
Line4
Line5
Line6

Example 3:

Blank  {Line0}
Loop 3 {Line1}
Label2 {Line2}
Blank  {Line3}
Loop 2 {Line4}  
Label1:{Line5}
Blank  {Line6}
Jump Label1 {Line7}
Blank  {Line8}
Jump Label2 {Line9}
Blank  {Line10}

Output I need:

Line0
Line1
Line2
Line3
Line4
Line5
Line6
Line7
Line5
Line6
Line7
Line8
Line9
Line2
Line3
Line4
Line5
Line6
Line7
Line5
Line6
Line7
Line8
Line9
Line2
Line3
Line4
Line5
Line6
Line7
Line5
Line6
Line7
Line8
Line9
Line10

I tried to implement @Samy Arous method from here: Using Python to Parse a File for Nested Loops but couldn't implement it so far.

Answer 1

I found it easier without regex:

import sys

infile = sys.stdin

def extract(line):
    return line[line.find('{') + 1: line.rfind('}')]

for first in infile:
    if first.startswith('Loop '):
        break
    else:
        print extract(first)

count = int(first.split()[1])
lines = [extract(first)] + map(extract, infile)

while count > 0:
    print '\n'.join(lines)
    count -= 1
