details about coded lines

Hello, well i have tested the code below which does the following :

 the data.configure.camera=true argument is changed into data.configure.camera=false in an Instructions file.

However , i would like to know if someone can describe the code lines below in order that i can understand properly which coded line does what please?

Thanx.

Here is the code below which i used:

def getInstructions(inp): --line 1 does what ?

    store = {} --line 2 does what ?

    try: -- line 3 does what ?

      configInput = open(inp) --line 4 does what ?

      for line in configInput.readlines():

          (key, val) = line.strip().split("=")
          store[key.strip()] = val.strip()
      configInput.close()
    except: pass
    return store
def putInstructions(out, store):
    configOutput = open(out, "w")
    for key in store.keys():
        line = key + "=" + store[key] + "\n"
        configOutput.write(line)
    configOutput.close()
fInstructions = "C:\\Users\\Richi\\Astrator\\Instructions.txt"
# step 1: fetch current instructions
instructions = getInstructions(fInstructions)
# step 2: modify instructions
instructions["data.configure.camera"] = "false"
# one might add additional instructions
instructions["data.configure.newoption"] = "true"
# step 3: write the instructions back to file
putInstructions(fInstructions, instructions)
