Python Celsius to Fahrenheit, Python3 os.rename() method

Python Celsius to Fahrenheit

The following example demonstrates how to convert Celsius to Fahrenheit:

# -*- coding: UTF-8 -*-

# Filename : test.py
# author by : www.w3cschool.cn

# User input temperature in Celsius

# Receive user income
celsius = float(input('Enter temperature in Celsius: '))

# Calculate temperature in Fahrenheit
Fahrenheit = (celsius * 1.8) + 32
print('%0.1f Celsius to Fahrenheit is %0.1f' %(celsius,fahrenheit))

The output of executing the above code is:

Enter temperature in Celsius: 38
38.0 Celsius to Fahrenheit is 100.4

In the above example, the formula for converting Celsius to Fahrenheit is celsius * 1.8 = fahrenheit - 32. So get the following formula:

centigrade = (Fahrenheit - 32) / 1.8

Python3 os.rename() method

---

overview

The os.rename() method is used to name a file or directory from src to dst, if dst is an existing directory, OSError will be thrown.

grammar

The syntax of the rename() method is as follows:

os.rename(src, dst)

parameter

• src  -- directory name to modify

• dst  -- the modified directory name

return value

The method has no return value

example

The following example demonstrates the use of the rename() method:

#!/usr/bin/python3

import os, sys

# list directories
print ("The directory is: %s" %os.listdir(os.getcwd()))

# double naming
os.rename("test","test2")

print ("Renamed successfully.")

# List the renamed directory
print ("The directory is: %s" %os.listdir(os.getcwd()))

The output of executing the above program is:

The directory is:
[  'a1.txt','resume.doc','a3.py','test' ]
Renaming succeeded.
[  'a1.txt','resume.doc','a3.py','test2' ]
