Python String Capitalize As we have seen in the above table, the capitalize method returns the copy of the string, with the first character in uppercase, and the rest of the characters in lowercase. Once we learn to use the method and see the output, we would simply understand what the method has to do. […]

Python String Methods When we are dealing with some strings, there are many operations that we might require to do, like converting the string into uppercase or lowercase, capitalizing, getting some substring from the given string, or finding if some string is present in another string, and many more things. These things can be achieved

Python Escape Sequence Basically, when we are writing strings, we might come across some situations, where we need to insert something into the string, which we cannot do directly, or if we are required to format our string in some way, we would want to make use of the escape sequences. The thing is that

Python String Slicing String slicing simply means that we are getting a range of characters with the specified indexes. Here, we are going to provide the starting index and the ending index (note that the ending index is not included). This is like we are saying that from the given string, we want another string,

String Concatenation When we use the + operator with the numbers, we are just performing the addition. For example, 5 + 6 is 11. But what if we are using the same + operator with the strings? Well, this would be something called string concatenation. This simply means that we are joining the two strings.

At times, we might require to deal with the strings, in our python programs. We can say that Python Strings is one of the most used, and most popular types of data in python. In fact, when we are writing some print function, or we are writing the input function, we are probably making use

Python Dictionary values Now, we are going to have a look at the values method. The values method is going to give us a view object of values of the dictionary. The object contains the values of the dictionary. Let’s have a look at a sample program, which would help us better understand the keys

Python Dictionary update Now, we are going to learn about the update method, in relation to the dictionary. With the update method, we can insert the specified item into the dictionary. These specified items can be a dictionary or some iterable object with key-value pairs. Let’s have a look at an example, where we would

Python Dictionary setdefault Now, we are going to learn about the setdefault method. If we want to access the element of the dictionary, we can do it very easily, using the setdefault method. Using the setdefault method, we get the value of the element corresponding to the specified key, if the key is present. But

Python Dictionary popitem Now, we are going to learn about the popitem method. Whenever we are required to remove the last added key-value pair from the dictionary, we can do that using the popitem method. So, we can simply say that the popitem method removes the last inserted key-value pair from the dictionary. Remember, if
