To calculate the length of an array in Python, you can use afor loop. First, create an array usingarray()function and set the length to'0'. Then, apply for loop over an array and for each iteration,increment the loop by 1and increase the length value. Finally, we can get the lengt...
To get the length of a list in Python, you can use the len(list) function. The len() function works similarly with other data structures, including tuples, sets, and dictionaries. The list's size is not fixed; the user can add or remove data to the list during execution time. The ...

Now, we create a 3rd column named Length and use the os.map(len) function that tells the length of the list column in the dataframe. df["Length"] = df.os.map(len) df Output: | index | os | Length | | --- | --- | --- | | 2013-12-22 15:25:02 | ubuntu,mac-osx...
