How can i change the following code to look at all the .log files in the directory and not just the one file? i need to loop through all the files and delete all lines that do not contain "step4". See this answer for a comprehensive ways to iterate over a dataframe. the most performant way is probably itertuples(). following is an example where a nested dictionary is created using a loop on the grouped dataframe: out = {} for k, g in grouped: # loop over groupby out[k] = {} for row in g.itertuples(): # loop over dataframe. When you iterate through dictionaries using the for in syntax, it always iterates over the keys (the values are accessible using dictionary[key]). to iterate over key value pairs, use the following:.

How can i iterate over a string in python (get each character from the string, one at a time, each time through a loop)?.
