Solution 1:

Use the fileinput module's inplace functionality. Refer Optional in-place filtering section at fileinput. The example below deletes the first line from a file:

import fileinput
import sys

for line_number, line in enumerate(fileinput.input('myFile', inplace=1)):
  ifline_number== 0:
    continueelse:
    sys.stdout.write(line)

Solution 2:
