ConfigParser.NoSectionError: No section: 'Default'

[degenaro]

I'm stuck. If I try to add an option to section Default I get the below error. But I also get an error when I try to first add section Default. Please advise.

#!/usr/bin/env python
import ConfigParser
config = ConfigParser.ConfigParser()
section = 'Default'
option = 'foo'
value = 'bar'
config.set(section, option, value)

Output:
...
    raise NoSectionError(section)
ConfigParser.NoSectionError: No section: 'Default'

Try code like the following. Please note that you are using Python 2.

For Python 3 'ConfigParser.' becomes lower case 'configparser.' (configparser dot) and import ConfigParser becomes import configparser

'Default' must be 'DEFAULT' (all caps)
You can also use ConfigParser.DEFAULTSECT

Python 2 code follows:

# Reference: https://python-forum.io/Thread-ConfigParser-NoSectionError-No-section-Default
# Reference Python 2: https://docs.python.org/2/library/configparser.html
# Reference Python 3: https://docs.python.org/3/library/configparser.html

# The following is Python 2 code
import ConfigParser

config = ConfigParser.ConfigParser()

section = "DEFAULT"
option = 'foo'
value = 'bar'
config.set(section, option, value)

section = ConfigParser.DEFAULTSECT
option = 'foo2'
value = 'bar2'
config.set(section, option, option)

section = "DEFAULT"
foo_value = config.get(section,'foo')
foo_value = config.get(section,'foo')
print("section {} foo_value = {}".format(section, foo_value))

foo2_value = config.get(section,'foo2')
print("section {} foo2_value = {}".format(section, foo2_value))



section = 'xyz'
option = 'abc'
value = 'abcbar'
config.add_section(section)
config.set(section, option, value)

option = 'abc2'
value = 'abcbar2'
config.set(section, option, value)

foo_value = config.get(section,'abc')
print("section {} foo_value = {}".format(section, foo_value))

foo2_value = config.get(section,'abc2')
print("section {} foo2_value = {}".format(section, foo2_value))

print("Done")

Output:
section DEFAULT foo_value = bar
section DEFAULT foo2_value = foo2
section xyz foo_value = abcbar
section xyz foo2_value = abcbar2
Done

Python 3 code follows (output is identical):

# Reference: https://python-forum.io/Thread-ConfigParser-NoSectionError-No-section-Default
# Reference Python 2: https://docs.python.org/2/library/configparser.html
# Reference Python 3: https://docs.python.org/3/library/configparser.html

# The following is Python 2 code
import configparser

config = configparser.ConfigParser()

section = "DEFAULT"
option = 'foo'
value = 'bar'
config.set(section, option, value)

section = configparser.DEFAULTSECT
option = 'foo2'
value = 'bar2'
config.set(section, option, option)

section = "DEFAULT"
foo_value = config.get(section,'foo')
foo_value = config.get(section,'foo')
print("section {} foo_value = {}".format(section, foo_value))

foo2_value = config.get(section,'foo2')
print("section {} foo2_value = {}".format(section, foo2_value))



section = 'xyz'
option = 'abc'
value = 'abcbar'
config.add_section(section)
config.set(section, option, value)

option = 'abc2'
value = 'abcbar2'
config.set(section, option, value)

foo_value = config.get(section,'abc')
print("section {} foo_value = {}".format(section, foo_value))

foo2_value = config.get(section,'abc2')
print("section {} foo2_value = {}".format(section, foo2_value))

print("Done")
