• Read CSV from its location on your machine. To read a CSV file locally stored on your machine pass the path to the file to the read_csv() function. You can pass a relative path, that is, the path with respect to your current working directory or you can pass an absolute path.
• Read CSV from a URL. You can also read a CSV file from its URL. Pass the URL to the read_csv() function and it’ll read the corresponding file to a dataframe.
• Read a CSV file without a header. In the above example, you saw that if the dataset does not have a header, the read_csv() function infers it by itself and uses the first row of the dataset as the header.
• Read a CSV file and give custom column names. You can give custom column names to your dataframe when reading a CSV file using the read_csv() function.
• Read CSV with a column as index. You can also use a column as the row labels of the dataframe. Pass the column name to the index_col parameter. Going back to the Iris.csv we downloaded from Kaggle.
• Read only a subset of columns of a CSV. You can also specify the subset of columns to read from the dataset. Pass the subset of columns you want as a list to the usecols parameter.
• Read only the first n rows of a CSV. You can also specify the number of rows of a file to read using the nrows parameter to the read_csv() function. Particularly useful when you want to read a small segment of a large file.
