How fast can someone learn or excel in something completely depends on one’s interest in learning, dedication and persistence.Now, how long does it take to learn Python depends on how much do you want to learn.The basics of Python which include functions, loops, conditional statements, datatypes, etc., would take about one to two weeks on average for a newbie. Again, this depends on how much time do you devote and your persistence in learning.If you aspire to learn Python in detail, it would take few months to learn Python. There is no end to learning Python as it is too ... Read More
Yes, Python is a scripting language.Scripting language v/s Programming languageThe first question which strikes into the mind is, what is the difference between programming and scripting language. The only difference which exists is that the scripting language does not require any compilation, it is directly interpreted.For example, the programs written in a language such as C++ are compiled before execution whereas the programs written in scripting languages such as Python or JavaScript are directly interpreted and are not compiled.Why is Python a scripting language?A scripting language is one that is interpreted. Python is an interpreted language. Python uses an interpreter ... Read More
When it is required to find the 'K'th column product in a list of tuple, a simple list comprehension and a loop can be used.A tuple is an immutable data type. It means, values once defined can't be changed by accessing their index elements. If we try to change the elements, it results in an error. They are important contains since they ensure read-only access. A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on).A list of tuple basically contains tuples enclosed in a list.The list comprehension ...

When it is required to remove nested record/tuples from a tuple of tuple, a simple loop and the 'isinstance' method and the enumerate method can be used.The enumerate method adds a counter to the given iterable, and returns it. The 'isinstance' method checks to see if a given parameter belong to a specific data type or not.Below is a demonstration of the same −ExampleLive Demotuple_1 = (11, 23, (41, 25, 22), 19) print("The tuple is : ") print(tuple_1) my_result = tuple() for count, elem in enumerate(tuple_1): if not isinstance(elem, tuple): my_result = my_result + ...

C programming is a general-purpose, procedural, imperative computer programming language. In C language, we see thatStatements are terminated with semicolons.C is case sensitiveIndentation is ignored by the compiler.Strings are placed in double quotes.Library functions are lowercase.Newlines are handled via Format of CThe format of C programming language is explained below −SemicolonsSemicolons are very important in C.It tells the compiler, where one statement ends and the next statement begins.If we fail to place the semicolon after each statement, you will get compilation errors.Case SensitivityC is a case sensitive language. Although, int compiles, "Int”, "INT” or any other variation will not be ... Read More
A palindrome is nothing but any word, number, sentence, or other sequence of characters that reads the same backward as forward.In this programming, we are trying to enter a number from console, and assign that number to temp variable.If number is greater than zero, apply the logic given below −while(n>0){ r=n%10; sum=(sum*10)+r; n=n/10; }If temp=sum, then the given number is a palindrome. Otherwise, it is not a palindrome.ExampleFollowing is the C program for verification of a value being palindrome −#include #include void main(){ int n, r, sum=0, temp; printf("Enter a number: "); scanf("%d", &n); ...

C header files include some predefined functions. For example, printf() and scanf() functions are defined in the stdio.h header file.Each header files in C contains different predefined functions to make programs simple to understand.When a header file is included two times in a C program, the second one gets ignored. In actual, the #, called the include, preceding a header file ensures that it is included only once during the compilation process.Example 1Following is the C program for computing an average of three numbers − Live Demo#include #include //header file included twice ,ignored by compiler main(){ int a, b, c, ...

Searching technique refers to finding a key element among the list of elements.If the given element is present in the list, then the searching process is said to be successful.If the given element is not present in the list, then the searching process is said to be unsuccessful.C language provides two types of searching techniques. They are as follows −Linear searchBinary searchLinear SearchSearching for the key element is done in a linear fashion.It is the simplest searching technique.It does not expect the list to be sorted.Limitation − It consumes more time and reduce the power of system.Input (i/p)Unsorted list of ...

Random accessing of files in C language can be done with the help of the following functions −ftell ( )rewind ( )fseek ( )ftell ( )It returns the current position of the file ptr.The syntax is as follows −int n = ftell (file pointer)For example, FILE *fp; int n; _____ _____ _____ n = ftell (fp);Note − ftell ( ) is used for counting the number of characters which are entered into a file.rewind ( )It makes file ptr move to beginning of the file.The syntax is as follows −rewind (file pointer);For example, FILE *fp; ----- ----- ...

File is a collection of records (or) is a place on hard disk, where data is stored permanently. By using C commands, we can access the files in different ways.Operations on filesThe operations that can be carried out on files in C language are as follows −Naming the file.Opening the file.Reading from the file.Writing into the file.Closing the file.SyntaxThe syntax for opening and naming file is as follows −FILE *File pointer;For example, FILE * fptr;File pointer = fopen ("File name”, "mode”);For example, fptr = fopen ("sample.txt”, "r”);FILE *fp; fp = fopen ("sample.txt”, "w”);The syntax for reading from file is as ...
