This post introduces two ways to open multiple files in Python.
- “with open” # do not need to bother to close the file(s) if use “with open”
with open("datafile.csv" , "r") as f: f.read() with open("datafile2.csv" , "r") as f2: f2.read()
try: with open('file.csv', 'w') as f, open('file2.csv', 'w') as f2: do_something() except IOError as e: print 'Operation failed: %s' % e.strerror
- “open” # need to close the file when use open.
f = open("datafile.csv" , "r") f2 = open("datafile2.csv" , "r") f.read() f2.read() f.close() f2.close()
