Printing double quotes is tricky, as it itself is required as part of syntax to print the strings by surrounding them. In this article we will see how these double quotes can be printed using print statement.The below scenarios will not print the double quote. The first two lines of code will give no output while the last one will through error.Example Live Demoprint(" ") print(" " " ") print(""aString"")OutputRunning the above code gives us the following result −;print(""aString"") ^ SyntaxError: invalid syntaxBut if we surround the strings with proper quotes as shown below, then the quotes can themselves get printed. ...

A bigram is formed by creating a pair of words from every two consecutive words from a given sentence. In python, this technique is heavily used in text analytics. Below we see two approaches on how to achieve this.Using enumerate and splitUsing these two methods we first split the sentence into multiple words and then use the enumerate function to create a pair of words from consecutive words.Example Live Demolist = ['Stop. look left right. go'] print ("The given list is : " + str(list)) # Using enumerate() and split() for Bigram formation output = [(k, m.split()[n + 1]) for m ...

If we print a given list of strings as it is, we have to use quotes and fill in a pair of matching quotes appropriately. We can avoid using quotes in the print statements by following two approaches.Using join()The join method helps us in printing the output of list elements by using any separator we choose. In the below example we choose ** as separator.Example Live Demolist = ['Mon', 'Tue', 'Wed'] # The given list print("The given list is : " + str(list)) print("The formatted output is : ") print(' ** '.join(list))OutputRunning the above code gives us the following result −The ...

It is a bitwise right shift operator. The bit pattern is shifted towards right by number of places stipulated by operand on right. Bits on left are set to 0For example a=60 (00111100 in binary), a>>2 will result in 15 (00001111 in binary)>>> a=60 >>> bin(a)result #39;0b111100' >>> b=a>>2 >>> bin(b) '0b1111'
Instead of hard coding the path to a file to be used by a python program, we can allow the user to browse the os folder structure using a GUI and let the user select the file. This is achieved using the tkinter module in which we define a canvas and put a button on it to browse the files.In the below program, we define a file opener function. We only use this function to open a text file as python can read the content of a text file and print it out in a much readable manner. We can ... Read More
Let us first create a table −mysql> create table DemoTable -> ( -> MonthNumber int -> ); Query OK, 0 rows affected (1.68 sec)Insert some records in the table using insert command −mysql> insert into DemoTable values(10); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable values(1); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable values(9); Query OK, 1 row affected (0.09 sec) mysql> insert into DemoTable values(6); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable values(8); Query OK, 1 row affected (0.09 sec) mysql> insert into DemoTable values(5); ...

Following is an example which compares Strings and portion of strings in Java? Explain with an example.ExampleLive Demopublic class StringDemo { public static void main(String[] args) { String str1 = "tutorials point"; String str2 = str1.substring(10); int result = str1.compareTo(str2); // prints the return value of the comparison if (result < 0) { System.out.println("str1 is greater than str2"); } else if (result == 0) { System.out.println("str1 is equal to str2"); } else { System.out.println("str1 is less than str2"); } } }Outputstr1 is less than str2
You can compare two Strings in Java using the compareTo() method, equals() method or == operator.The compareTo() method compares two strings. The comparison is based on the Unicode value of each character in the strings. The character sequence represented by this String object is compared lexicographically to the character sequence represented by the argument string. The result is a negative integer if this String object lexicographically precedes the argument string.The result is a positive integer if this String object lexicographically follows the argument string. The result is zero if the strings are equal, compareTo returns 0 exactly when the equals(Object) method would ... Read More
MySQL AND is used in WHERE to fetch a record by filtering using multiple conditions. Let us first create a table−mysql> create table DemoTable -> ( -> Id int, -> Name varchar(20) -> ); Query OK, 0 rows affected (0.70 sec)Insert some records in the table using insert command −mysql> insert into DemoTable values(101, 'Chris'); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable values(102, 'David'); Query OK, 1 row affected (0.51 sec) mysql> insert into DemoTable values(103, 'Bob'); Query OK, 1 row affected (0.14 sec)Display all records from the table using select statement ...

You can change the cases of the letters of a word using toUpperCase() and toLowerCase() methods.Split each word in the string using the split() method, change the first letter of each word to lower case and remaining letters to upper case.ExampleLive Demopublic class Sample{ public static void main(String args[]){ String sample = "Hello How are you"; String[] words = sample.split(" "); String result = ""; for(String word:words){ String firstSub = word.substring(0, 1); String secondSub = word.substring(1); result = result+firstSub.toLowerCase()+secondSub.toUpperCase()+" "; } System.out.println(result); } }OutputhELLO hOW aRE yOU
