# Getting Started with python3 # 3 Try Advanced Computations Using Import Statements

Hi, my name is beatbox4108.
This time, I would like to write about *advanced calculation* using __import statement __.

# What is the import statement in the first place?

You can use the __import statement __ to execute other python files (.py .pyw).

## Import statement type

ʻImport module name`: You can refer to it in a python file as `

module name`. ʻImport module name as reference name`

:
You can refer to it in a python file as a `reference name`

.
`from module name import function name`

:
Imports the specified function.
`from module name import *`

:
Import all functions in `module name`

.

## Do advanced calculations immediately.

There is a math module in the python standard library, so I would like to import it and use it.
Please write like this.

`main.py`

```
import math as m
print("Pi:",m.pi)#3.141592653589793
print("3.Round up 5:",m.ceil(3.5))#4
print("3.Devaluation of 5:",m.floor(3.5))#3
print("3 to the 5th power:",m.pow(3,5))#243.0(The power of the math module is returned as a float type. Built-in pow function,**You can also use operators.)
print("Make 180 degrees radians:",m.radians(180))#3.141592653589793
print("180 radians at an angle:",m.degrees(3.141592653589793))#180.0
print("sin 100:",m.sin(100),",cos 100:",m.cos(100),",tan 100",m.tan(100))
#sin 100: -0.5063656411097588 ,cos 100: 0.8623188722876839 ,tan 100 -0.5872139151569291
print("Square root of 9",m.sqrt(9))#3
```

... you can do it well.
Next, I haven't posted the table of arithmetic operators even once, so I'd like to post it.

## Table of arithmetic operators

operator |
function |
Example |
Description |

+(Unary plus operator) |
Positive number |
+x |
Specify a positive number. It does not change even if a code is added. |

-(Unary minus operator) |
Sign inversion |
-x |
Invert the sign of the value of a. |

+ |
addition |
x + y |
Add y to x. |

- |
subtraction |
x - y |
Subtract y from x. |

* |
multiplication |
x * y |
Multiply x by y. |

/ |
division |
x / y |
Divide x by y. |

// |
Integer division(If the expression contains a decimal number, it can be of type float.) |
x // y |
Truncate the decimal from the result of dividing x by y. |

** |
multiplier |
x**y |
Find x to the yth power. |

% |
Surplus |
x % y |
Find the remainder of x divided by y |

This time, I would like to end with this. Stay tuned for the next time!
