NSE functions should be used in interactive programming. However, when developping new functions in a new package, it's better to use SE version. Load dplyr and lazyeval : library(dplyr) library(lazyeval) Filtering NSE version filter(mtcars, cyl == 8) filter(mtcars, cyl < 6) filter(mtca...

The Problem You have a set of things to do (activities). Each activity has a start time and a end time. You aren't allowed to perform more than one activity at a time. Your task is to find a way to perform the maximum number of activities. For example, suppose you have a selection of classes to ch...

Numbers have four types in Python. Int, float, complex, and long. int_num = 10 #int value float_num = 10.2 #float value complex_num = 3.14j #complex value long_num = 1234567L #long value

String are identified as a contiguous set of characters represented in the quotation marks. Python allows for either pairs of single or double quotes. Strings are immutable sequence data type, i.e each time one makes any changes to a string, completely new string object is created. a_str = 'Hello ...

A list contains items separated by commas and enclosed within square brackets [].lists are almost similar to arrays in C. One difference is that all the items belonging to a list can be of different data type. list = [123,'abcd',10.2,'d'] #can be a array of any data type or single data type. li...

Lists are enclosed in brackets [ ] and their elements and size can be changed, while tuples are enclosed in parentheses ( ) and cannot be updated. Tuples are immutable. tuple = (123,'hello') tuple1 = ('world') print(tuple) #will output whole tuple. (123,'hello') print(tuple[0]) #will outp...

Dictionary consists of key-value pairs.It is enclosed by curly braces {} and values can be assigned and accessed using square brackets[]. dic={'name':'red','age':10} print(dic) #will output all the key-value pairs. {'name':'red','age':10} print(dic['name']) #will output only value with 'nam...

In the following, weight is declared as a mutable field. type person = { name: string; mutable weight: int };; Remark: As far as design is concerned here, one would consider the fact that a person's name isn't likely to change, but their weight is.

Initializing a record with mutable fields isn't different from a regular record initialization. let john = { name = "John"; weight = 115 };;

To assign a new value to a mutable record field, use the <- operator. john.weight <- 120;; Note: The previous expression has a unit type.

Generally tf.gather gives you access to elements in the first dimension of a tensor (e.g. rows 1, 3 and 7 in a 2-dimensional Tensor). If you need access to any other dimension than the first one, or if you don't need the whole slice, but e.g. only the 5th entry in the 1st, 3rd and 7th row, you are b...
