1. Menjalankan Phyton
Program python dijalankan oleh “Interpreter”. Saat awal menjalankan python kita akan menjalankan mode interaktif yang dapat langsung dijalankan. Di bagian atas interpreter ada tulisan copyright dan di bawahnya ada tanda >>>
Python 2.4.1 (#2, Mar 31 2005 , 00:05:10) [GCC 3.3 20030304 (Apple Computer, Inc. build 1666)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> print "Hello World" Hello World >>>
Dengan mengetik kata-kata contohnya “Hello World” dan tekan enter program langsung dijalankan.
2. Operator-operator dasar Phyton
Operator perbandingan
Operator perbandingan digunakan untuk membandingkan dua objek/elemen dalam bahasa pemrogaman
| Comparison | Meaning | Notes |
|---|---|---|
| < | strictly less than | (1) |
| <= | less than or equal to | |
| > | greater than or equal to | |
| == | equal to | |
| != or <> | not equal to | |
| is | object identity | (2) |
| is not | negated object identity | (2) |
Boolean Operator
Boolean operator menghasilkan ouput benar (True) atau (False), digunakan untuk mencari apakah objek yang diperbandingkan memenuhi operator Boolean.
| Value Or Operator | Evaluates to | Notes |
|---|---|---|
| build-in bool(expr) | true if expr is true, False otherwise | see True, False |
| None, numeric zeros, empty sequences and mapping | consider False | |
| all other | consider True | |
| not x | True if x is False, else False | |
| x or y | if x is False then y, else x | (1) |
| x and y | if x is False then x, else xy/td> | (1) |
Operator bit
| Operation | Result |
|---|---|
| ~x | the bits of x inverted |
| x^y | bitwise exclusive or of x and y |
| x&y | bitwise and of x and y |
| x|y | bitwise or of x and y |
| x<<n | shifted left by n bits |
| x>>n | x shifted right by n bits |
Operator Numerikal
Operator numerical digunakan untuk mengoperasikan nilai-nilai dalam objek Phyton. Misalnya saja perkalian, pembagian, pertambahan dan lain-lain, daftar operator numerical adalah sebagai berikut :
| Operation | Result |
|---|---|
| abs(x) | the absolute value of x |
| int(x) | x converted to integer |
| long(x) | x converted to long integer |
| float(x) | x converted to floating point |
| -x | x negated |
| +x | x unchanged |
| x+y | the sum of x and y |
| x-y | difference of x and y |
| x*y | product of x and y |
| x/y | true division of x by y: 1/2 -> 0.5(1) |
| x//y | floor division operator: 1//2 -> 0(1) |
| x%y | x modulo y |
| divmod(x, y) | the tuple (x//y, x%y) |
| x**y | x to power y (the same as pow (x,y)) |
