Methods

__init__([data, dtype, copy, name, …])
agg([func, axis])
aggregate([func, axis])
all()
any()
astype(dtype[, copy])	Create an Index with values cast to dtypes.
check_monotonic([decreasing, strict])	Check if values in the object are monotonic increasing or decreasing.
copy()
copy_from(obj)
copy_to(target)
drop(labels[, errors])	Make new Index with passed list of labels deleted.
drop_duplicates([keep, method])	Return Index with duplicate values removed.
dropna([how])	Return Index without NA/NaN values.
duplicated([keep])	Indicate duplicate index values.
execute([session])
fillna([value, downcast])	Fill NA/NaN values with the specified value.
isna()	Detect missing values.
map(mapper[, na_action, dtype, memory_scale])	Map values using input correspondence (a dict, Series, or function).
max([axis, skipna])
memory_usage([deep])	Memory usage of the values.
min([axis, skipna])
notna()	Detect existing (non-missing) values.
rebalance([factor, axis, num_partitions, …])	Make Data more balanced across entire cluster.
rechunk(chunk_size[, threshold, …])
rename(name[, inplace])	Alter Index or MultiIndex name.
set_names(names[, level, inplace])	Set Index or MultiIndex name.
tiles()
to_frame([index, name])	Create a DataFrame with a column containing the Index.
to_pandas([session])
to_series([index, name])	Create a Series with both index and values equal to the index keys.
value_counts([normalize, sort, ascending, …])	Return a Series containing counts of unique values.
