How to iterate column names in pandas

In order to iterate column names in pandas, use

for column in df.columns:
    print(columns)

For example, for the TechOverflow pandas time series example dataset, df.columnswill be

Index(['Sine', 'Cosine'], dtype='object')

so iterating over the columns using

# Load pre-built time series example dataset
df = pd.read_csv("https://datasets.techoverflow.net/timeseries-example.csv", parse_dates=["Timestamp"])
df.set_index("Timestamp", inplace=True)

# Iterate over columns
for column in df.columns:
    print(column)

will print

Sine
Cosine

Note that df.columns will notshow the index column!
