How to Resolve \'TypeError: string indices must be integers\' Error when Retrieving Yahoo Finance Data with Pandas Datareader?

Getting "TypeError: string indices must be integers" Error when Fetching Yahoo Finance Data with Pandas Datareader

When using Pandas Datareader to acquire stock data from Yahoo Finance, an error indicating "string indices must be integers" may occur. This occurs when attempting to access stock data using a string index rather than an integer.

Solution

Ensure that the symbols parameter in get_data_yahoo is passed as a list of strings rather than a single string. For instance, instead of symbols="TATAELXSI.NS", use symbols=["TATAELXSI.NS"].

Alternative Fix Using pdr_override() Method

An alternative workaround method includes using the pdr_override function to specify the stock symbol as a string:

<code class="python">import pandas_datareader.data as pdr

symbols = ["TATAELXSI.NS"]

with pdr.pdr_override():
    data = pdr.get_data_yahoo(symbols=symbols, start=start, end=end)</code>

This method allows for using a string as the symbol argument by instructing the function to treat it as an integer.

Additional Notes

• Ensure that Pandas Datareader is up-to-date to avoid compatibility issues.
• Verify that the symbols parameter contains valid stock symbols.
• Check if the Yahoo Finance API is temporarily unavailable.
