Write the experimental procedure to find the image distance using concave mirror when an object is kept in front of it on its principal axis at different locations. code example

Example 1: You will be passed the filename P, firstname F, lastname L, and a new birthday B. Load the fixed length record file in P, search for F,L in the first and change birthday to B. Hint: Each record is at a fixed length of 40. Then save the file.

# You will be passed the filename P, firstname F, lastname L, and a new birthday B.
# Load the fixed length record file in P, search for F,L in the first and change birthday to B.
# Hint: Each record is at a fixed length of 40.
# Then save the file.
import re
file1 = open(P, 'r') 
data = file1.read() 
file1.close() 
found = re.findall(F + ' *' + L + ' *', data) 
chars = len(found[0])
beginChar = data.find(found[0])
birthday = data[beginChar + chars:beginChar + chars + 8]
data = data.replace(birthday, B)
file1 = open(P, 'w')
file1.write(data)
file1.close

Example 2: which gopros have the same form factor and port alignment
