the concatenation of two lists using the+operator oritertools.chain(), and the combination of a list with a set. Additionally, you will also learn using thestrip()method for removing leading
explicitly alignedto a set of labels, or the user can simply ignore the labels and let`Series`, `DataFrame`, etc. automatically align the data for you incomputations.- Powerful, flexible group by functionality to perform split-apply-combineoperations on data sets, for both aggregating and trans...
In Python, an operator may be a symbol, a combination of symbols, or a keyword, depending on the type of operator that you’re dealing with.For example, you’ve already seen the subtraction operator, which is represented with a single minus sign (-). The equality operator is a double ...
. However, this isn’t a requirement for combinations of flags, like Role.ADMIN. In the above example, you defined Role.ADMIN as a combination of roles. Its value results from applying the bitwise OR operator to the complete list of previous roles in the enumeration. IntFlag also supports ...

While working with python collections with elements, we might require operations to extract some information as a combination of tuple elements. In this program, we will perform the concatenation of two strings which are elements of the tuple. ...
We will be creating a program that will flatter the tuple and create a string with the flattened elements. In Python, we have multiple methods and ways to perform this task.Method 1: One method to solve the problem is by first creating a map of sum of elements of each tuple in Python...
a single value, but it is sometimes necessary to return more than one value. The only way to do this is to package the multiple values in a single data structure, then return that. Thus, you’re still returning one thing, even though it potentially contains many individual pieces of data...
Similarly, if we have multiple lists inside a list like: List = [ [1, 3, 5], [8, 5, 6], [7, 1, 6] ] #can be also viewed as | 1, 3, 5 | | 8, 5, 6 | | 7, 1, 6 | All the elements of the list can be accessed by below indices: ...
