1 00:00:01,200 --> 00:00:06,780 ‫Now, let's start learning pythons syntaxes by performing some basic arithmetic operations. 2 00:00:12,340 --> 00:00:19,060 ‫The most basic operation is addition of two numbers we can use, plus symbol to do that. 3 00:00:19,630 --> 00:00:26,330 ‫So we will write two plus two and we will execute this cell by pressing alt or enter. 4 00:00:28,510 --> 00:00:31,060 ‫You can see we are getting result as an output. 5 00:00:33,230 --> 00:00:35,650 ‫Second, arithmetic operation is substraction. 6 00:00:36,500 --> 00:00:43,660 ‫We can use minus symbol, so if it write five, minus two and execute it, we are getting the result 7 00:00:45,970 --> 00:00:47,440 ‫Next is multiplication. 8 00:00:47,710 --> 00:00:49,390 ‫We can use asterisk symbol 9 00:00:50,600 --> 00:00:56,500 ‫To multiply two numbers, if we write three into four and execute it, 10 00:00:57,230 --> 00:00:59,110 ‫We are getting twelve as our output. 11 00:01:01,010 --> 00:01:02,300 ‫Next is division. 12 00:01:04,200 --> 00:01:06,490 ‫We'll write five slash two. 13 00:01:07,790 --> 00:01:12,760 ‫Now, to use power or exponential functions, we can use two asterisk symbols. 14 00:01:13,400 --> 00:01:16,490 ‫So if I write five asterisk asterisk two. 15 00:01:18,010 --> 00:01:20,290 ‫Means that we are squaring five. 16 00:01:21,220 --> 00:01:23,620 ‫Next is Modulus or reminder function. 17 00:01:24,490 --> 00:01:27,730 ‫It will return the remainder of the division. 18 00:01:28,420 --> 00:01:34,930 ‫So if I write five modulus two, we are getting one as our result. 19 00:01:35,380 --> 00:01:38,470 ‫So if we divide five by two, we get one. 20 00:01:38,560 --> 00:01:42,530 ‫As a reminder, we can also use multiple operators. 21 00:01:43,330 --> 00:01:48,730 ‫So I can write five into two plus four. 22 00:01:51,680 --> 00:01:56,180 ‫If I execute this command, I will get 14 as a result. 23 00:01:57,440 --> 00:02:01,500 ‫You can notice that Python is following the Boardmass rule. First 24 00:02:01,760 --> 00:02:03,380 ‫It is multiplying 5 and 2 25 00:02:03,980 --> 00:02:06,740 ‫Then it is adding 4 to that result. 26 00:02:09,290 --> 00:02:13,370 ‫It is better to use parentheses while using multiple operators. 27 00:02:14,210 --> 00:02:21,020 ‫So if we want to add two and four first and then multiply it with five, we can write five 28 00:02:21,560 --> 00:02:24,080 ‫and in parenthesis we can write two plus four. 29 00:02:26,680 --> 00:02:33,370 ‫You can see here we are first adding 2 and 4 which is 6, and then multiplying this number 30 00:02:33,460 --> 00:02:34,120 ‫with the five. 31 00:02:34,270 --> 00:02:36,220 ‫So the result is 30. 32 00:02:38,470 --> 00:02:42,910 ‫When you are using multiple operators, it is always recommend to use parenthesis. 33 00:02:45,330 --> 00:02:52,320 ‫We can also assign these values to variable so I can assign where one. 34 00:02:54,600 --> 00:02:55,430 ‫Equal to 2. 35 00:02:58,130 --> 00:02:59,580 ‫So now, my variable 36 00:02:59,630 --> 00:03:01,960 ‫where one is containing a value two. 37 00:03:02,420 --> 00:03:06,260 ‫If I just write where 1 and execute it, python will display it's value. 38 00:03:06,340 --> 00:03:10,160 ‫Well, you can see now we are getting two as an output. 39 00:03:12,670 --> 00:03:17,980 ‫We can also use arithmetic operators while defining the variable. 40 00:03:18,400 --> 00:03:26,910 ‫So if I just change the value of var1 to our previous argument, that is five into two plus four. 41 00:03:32,510 --> 00:03:36,340 ‫Our var 1 will now contain a value 14. 42 00:03:39,640 --> 00:03:42,680 ‫You can also notice that we have replaced the value 2 43 00:03:42,880 --> 00:03:43,920 ‫With Value 14. 44 00:03:44,500 --> 00:03:50,230 ‫So if you re assign value to some variable, it will just replace that value. 45 00:03:52,210 --> 00:03:55,410 ‫Now, python also supports comparison operators. 46 00:03:56,140 --> 00:03:59,890 ‫So if I write five greater than two. 47 00:04:02,470 --> 00:04:03,510 ‫The result is true. 48 00:04:05,590 --> 00:04:10,820 ‫Similarly, it also supports less than less than equal to and more than equal to. 49 00:04:11,290 --> 00:04:17,470 ‫So, for example, I can write three less than equal to 50 00:04:18,690 --> 00:04:21,720 ‫2 the result should be false. 51 00:04:23,650 --> 00:04:25,750 ‫And we are getting false as our output.
