In this article, we learned to read file contents from line 2 by using several built-in functions such as next(), readlines(), islice(), csv.reader() and different examples to skip the header line from the given files. This method can also be useful while reading the content of multiple CSV files. This method reads the file from line 2 using csv.reader that skips the header using next() and prints the rows from line 2. We use the sample.csv file to read the contents. John, 18, Science Example: Read the CSV File from Line 2 This even works for in-memory uploaded files while iterating over file objects. While using this function, the destination list’s size must be greater than the size of the source list. This is an efficient and pythonic way of solving the problem and can be extended to an arbitrary number of header lines. For such type of scenarios, package provides us with a function copy () that copies elements present in one list into the other list, such that elements have the same index in the new list as well. The first argument is the file to read the data, the second is the position from where the reading of the file will start and the third argument is None which represents the step. This method imports islice from itertools module in Python. We use the sample.txt file to read the contents. Example: Read the Text File from Line 2 using islice() Also, it uses unnecessary space because slice builds a copy of the contents. The drawback of this method is that it works fine for small files but can create problems for large files. This is a much more powerful solution as it generalizes to any line. As you can see in the below example, readlines, it denotes that the reading of the file starts from index 1 as it skips the index 0. This method uses readlines() to skip the header and starts reading the file from line 2. Eclipse is the IDE that the Java developers mostly prefer. We use the sample.txt file to read the contents. Eclipse Keyboard Shortcuts: Eclipse is IDE or Integrated Development Environment related to programming computers by Java developers. John, 18, Science Example: Read the Text File from Line 2 using readlines() This shows that the header of the file is stored in next(). Note: If you want to print the header later, instead of next(f) use f.readline() and store it as a variable or use header_line = next(f). This method uses next() to skip the header and starts reading the file from line 2. Example: Read the Text File from Line 2 using next() We will use the above files to read the contents. ![]() ![]() Now, let us look at four different ways to read a text file and a csv file from line 2 in Python. Sample CSV File //sample.csv Student Details of Class X Adding a new line in Java is as simple as including n, r, or rn at the end of our string. Sample Text File //sample.txt Student Details of Class X We will read a sample.txt file as well as a sample.csv file. Let us discuss four different methods to read a file from line 2. This article will show how you can skip the header row or the first line and start reading a file from line 2. In the case of reading files, the user can start reading a file either from the first-line or from the second line. We will use some built-in functions, some simple approaches, and some custom codes as well to better understand the topic. I hope you like the tutorial.In this article, we will learn how one can read a file from the second line in Python. Please follow C Programming tutorials or the menu in the sidebar for the complete tutorial series.Īlso for the example C programs please refer to C Programming Examples.Īn investment in knowledge always pays the best interest. The return in main() function returns zero because it is necessary to have a return value here because main has been given the return type int. We also see that the return type of func() is char because it is returning a character value. The function func() is returning the character value of the given number(here 110). In this program, we have two functions that have a return type but only one function is returning a value and the other is just used to terminate the function. Printf("Enter any ascii value in decimal: \n") Let’s implement an example to understand how break statement works in C language. The use of the break keyword in switch-case has been explained in the previous tutorial Switch – Control Statement.Īnother point to be taken into consideration is that the break statement when used in nested loops only terminates the inner loop where it is used and not any of the outer loops. ![]() ![]() It is mostly used in loops and switch-case to bypass the rest of the statement and take the control to the end of the loop. A break statement is used to terminate the execution of the rest of the block where it is present and takes the control out of the block to the next statement.
