String Formatting With String.Format Method in Python

Another way to format strings is the string.format method.This method indicates the places we want to change on a string with curly braces.For example, there is a variable named Linkedin below, and two sections are left blank with curly braces.We will place values in these sections with the string.format method. So how we do it?  We write the variable we want to format. Then we call the format m..

String Formatting With % Operator in Python

The format is a method that helps us insert a variable or value anywhere in a string expression.We can format using the percent sign.For example, there is a sentence below. We would like to leave the blank in this sentence anonymous.In other words, we do not want this empty part to remain costant ; we want to fill it with the vlaue we want in the next step. So how do we do this?  If we want to s..

We have learned in our previous lessons that we can perform arithmetic operations on string values.However, we should not have thought of these arithmetic operations mathematically.For example, aggregation was used to concatenate string values. You can also do this collection as follows:You can perform your operations from a shortcut by using the arithmetic operator before "equals". You can perf..

Strings have negative indexing as well as positive indexing.Positive indexing starts from the first character of the string value and the first index number is zero. We know this.In negative indexing, it starts from the last value and progresses to the beginning.Index numbers starts from -1 in negative indexing.We can index according to these index numbers :  Indexing using negative index nunber..

In Python, the process of accessing values, characters,  etc. in a data type is called indexing.Square brackets are used while indexing.And the index number of the value we want to reach is written in square brackets. For example, we want to reach teh first character of the value in the variable car below.Since insdex number starts from zero in Python, we wrote zero in square brackets. The proce..

The title() method converts only the first letter of the words in a string expression to uppercase     The strip() method in used to trim the values we want from the beginning and end of string values.    If we don't write anything inside the method, by default it removes all spaces to the left and right.     The strip() method can take a value in it. Trims all of this value at the begining and ..

Replace method is used to replace characters in string values.    It takes two values in it. The first is the value we want to change, and the other is new value.     For example, we wanted to get rid of the hypens between the letters of the name "joseph" below. And we did this request with the replace method.     In the Replace method, we can determine the number of changes we wnat to make on t..

Methods are various functions implemented on data structures. The first method we will learn in this context is the len method.    The Len method is called the abbreviation of the word lenght. It gives the length information of the objects we will put in it.    Spcae in strings are counted as characters.       Startwith() method takes a value in it. And based on the value it receives, it asks Py..

If the question we asked to Python is true, we get True, if false, we get False. These are Boolean values.There are also logical expression operators that we use with Booleans. These are "And, or, not" operators. When the And operators is used with Boolean values, if there is even one False in the values, the result is fales.If all booleans are true, it will output True.  The "or" operator is th..

Escape Sequence operations allow some opertaions on the textual expressions we want to output.You can see the most frequently used characters below. We will examine them in detail  \n ==> newline\t ==> tab\b ==> backline After the newline string is written anywhere in an expression, it moves the next expression to the bottom line  \n ==> newline For example, below, there are two sentences in pri..
