You can get the length (i.e., the number of elements) of a tuple using the built-inlen()function. For example, you can create a tuple with4elements, and then you use thelen()function to get the length of the tuple. # Using len() function technology= ('Spark','Pandas','Pyspark'...
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...
