Reading CSV Files#
CSV (Comma-Separated Values) files are a common format for station observations, climate indices, or manually processed data. They are simple text files organized in rows and columns and can be read using the pandas
library.
📥 Reading a CSV File#
Here’s how to read a CSV file using pandas
:
import pandas as pd
# Read a simple CSV file
df = pd.read_csv("../data/precip_timeseries.csv")
# Display the first few rows
print(df.head())
🧠Tips#
Use
parse_dates=['date']
if your file includes timestamps.Use
index_col='date'
if you want to treat the date as the DataFrame index.Use
sep="\t"
ordelimiter=','
to adjust for tab-delimited or nonstandard formats.
CSV is ideal for small datasets and quick exploratory work.
