To display the value of the step parameter of RangeIndex, use the index.step property in Pandas.At first, import the required libraries −import pandas as pdRangeIndex is a memory-saving special case of Int64Index limited to representing monotonic ranges. Create a range index with start, stop and step. The name is the name to be stored in the index.index = pd.RangeIndex(start=10, stop=30, step=2, name="data") Display the step parameter value −print("RangeIndex step value...", index.step)ExampleFollowing is the code −import pandas as pd # RangeIndex is a memory-saving special case of Int64Index limited to representing monotonic ranges. # Create a range index with start, ...

To display the value of the stop parameter of RangeIndex, use the index.stop property in Pandas.At first, import the required libraries −import pandas as pdRangeIndex is a memory-saving special case of Int64Index limited to representing monotonic ranges. Create a range index with start, stop and step. The name is the name to be stored in the index.index = pd.RangeIndex(start=5, stop=20, step=2, name="data") Display the RangeIndex −print("RangeIndex...", index)Display the stop parameter value −print("RangeIndex stop value...", index.stop) ExampleFollowing is the code −import pandas as pd # RangeIndex is a memory-saving special case of Int64Index limited to representing monotonic ranges. # Using ...

Suppose we have a list of numbers called nums, we have to return the list by swapping each consecutive even indexes with each other, and swapping each consecutive odd indexes with each other.So, if the input is like nums = [8, 5, 3, 4, 8, 9, 3, 6, 4, 7], then the output will be [3, 4, 8, 5, 3, 6, 8, 9, 4, 7]To solve this, we will follow these steps −for i in range 0 to size of nums - 2, increase by 4, doif i + 2 < size of nums, thenswap nums[i] and nums[i + 2]if ...

To display the value of the start parameter of RangeIndex, use the index.start property in Pandas. At first, import the required libraries −import pandas as pdRangeIndex is a memory-saving special case of Int64Index limited to representing monotonic ranges. Using RangeIndex may in some instances improve computing speed. Create a range index with start, stop and step.

To compute slice locations for input labels, use the index.slice_locs() method. At first, import the required libraries −import pandas as pdCreate Pandas index object −index = pd.Index(list('pqrstuvwxyz')) Display the Pandas index −print("Pandas Index...", index)Get the slice locations. The "start" is the label to begin with. The "end" is the label to end withprint("The slice locations with start and stop...", index.slice_locs(start='q', end='v')) ExampleFollowing is the code −import pandas as pd # Create Pandas index object index = pd.Index(list('pqrstuvwxyz')) # Display the Pandas index print("Pandas Index...", index) # Return the number of elements in the Index print("Number of elements ...

Suppose we have two lowercase strings s and t, they are of the same length. We can select one character from s and another from t and swap them. We can do this operation any number of times we want. Finally, we have to check whether it's possible to make the two strings same or not.So, if the input is like s = "abcd" t = "cdab", then the output will be TrueTo solve this, we will follow these steps −fre := a list containing frequencies of each elements present in concatenated string of s and tfor each cnt in ...

Suppose we have a list of numbers called nums and the elements in nums are sorted in ascending order. We also have another value k, we have to check whether any two elements taken from the list add up to k or not. The numbers can also be negative or 0. We have to solve this problem in constant amount of space usage.So, if the input is like nums = [-8, -3, 2, 7, 9] k = 4, then the output will be True, because if we take 7 and -3, then the sum is 7 + (-3) = 4, ...

Suppose we have a list of numbers called nums and also have a target value, we have to find the sum of the largest pair of numbers in nums whose sum is at most (target-1).So, if the input is like nums = [8, 3, 4, 9, 2] target = 8, then the output will be 7, because the sum of the largest pair of numbers less than 8 is 4 + 3 = 7.To solve this, we will follow these steps −sort the list numsp1 := 0p2 := size of nums - 1m := -infwhile p1 < p2, doif nums[p1] ...
