Hi Coursecademy. Its indeed a pleasure to write to a wonderful platform like this which has made coding for biologists and other non-computer core people much much easier. But now, I have a doubt on len() command. The dot notation is clear, but the length of a string containing more than one words is giving an output containing the number of letters as well as the number of spaces in between the words. This seems tricky. Will you please help me to rectify it? Thank you.

why is this tricky?

What do you want the number (length) of? Only alphanumeric characters? Punctuation as well? The length of each individual word?

len is designed to get the total count of everything in the string.

Just came across a glitch that may need some attention. I went to this page, and when I got to the part to do the script.py, information from another script.py was in the coding area. Therefore, I was not able to follow the directions, because the directions were based on having specific information pre-loaded to the script.py. Since this was different than what it was supposed to be, I could not get the correct answer. However, I was able to make it pop up right by going back to the previous page before Dot Notation, and then going back to the Dot Notation page. Then, the information that was supposed to originally be in the script.py was there. Thanks

I equally find this tricky and i think it’s because even though the len command is designed to count every character of the string, it output still fall short of what is obtainable. take for instance this "The Ministry of Silly Walks"
the len comman returned 27 on the console and it to be 25 i think

The Ministry of Silly Walks is 27 in length, why should this be 25? Even if you use a tool like this one, you will get 27. There really are 27 characters in this string

thanks. you’re actually correct as I have checked again, the characters are 27 and not 25

The reference to Monty Pythons’s Silly Walks sketch is funny. Both are python (fun fact: the creator of Python named Python after Monty Python.)
