What is a tab in programming?
Tab characters. The most known and common tab is a horizontal tabulation (HT) or character tabulation, which in ASCII has the decimal character code of 9, and may be referred to as Ctrl + I or ^I. In C and many other programming languages the escape code \t can be used to put this character into a string constant.
What is \t used for in C programming?
\t (Horizontal tab) – We use it to shift the cursor to a couple of spaces to the right in the same line. \a (Audible bell) – A beep is generated indicating the execution of the program to alert the user. \r (Carriage Return) – We use it to position the cursor to the beginning of the current line.
Is tab equal to 4 spaces?
Indentation: tabs vs spaces Java: 4 spaces, tabs must be set at 8 spaces. Both are acceptable.
What are tabs in Python?
The Python tab is divided into two parts: the input pane and the output pane. The input pane, the lower part of the tab, is used to type in and execute your Python statements. When you’ve done this, the statement and the output appears in the output pane, the upper part of the tab.
Is tabs or spaces better?
The analysis performed by the team at Stack Overflow found that programmers who use spaces instead of tabs are making more money. David Robinson, the data scientist who performed this study found that programmers using space over tabs made an average of 9 percent more each year than their tab using counterparts.
What is tabs vs spaces?
So, at the end of the day, tabs versus spaces is truly a matter of preference, however the tab is still the character specifically designed for indentation, and using one tab character per indentation level instead of 2 or 4 spaces will use less disk space / memory / compiler resources and the like.

Why are tabs bad in code?
Because it’s their preference. A convention they wish to be followed to keep uniformity (along with things like naming and brace style). Nothing more. Spaces are better than tabs because different editors and viewers, or different editor settings, might cause tabs to be displayed differently.
What is difference between space and tab?
Tabs need less characters and are formatted by users (some display as 2, some as 4 spaces), what can make some code look bad on some other environment. Spaces consume more KBs but look equal everywhere. Good editors have retab-functions to convert those.
How does tab work in Python?
In Python strings, the backslash “\” is a special character, also called the “escape” character. It is used in representing certain whitespace characters: “\t” is a tab, “\n” is a newline, and “\r” is a carriage return. Conversely, prefixing a special character with “\” turns it into an ordinary character.
