Overview

Checks for spaces inside ordinary round parentheses.

Examples:

EnforcedStyle: no_space (default)

# The `no_space` style enforces that parentheses do not have spaces.

# bad
f( 3)
g = (a + 3 )
f( )

# good
f(3)
g = (a + 3)
f()

EnforcedStyle: space

# The `space` style enforces that parentheses have a space at the
# beginning and end.
# Note: Empty parentheses should not have spaces.

# bad
f(3)
g = (a + 3)
y( )

# good
f( 3 )
g = ( a + 3 )
y()
