Question

i need a python code

For an exact conversion between "Fahrenheit temperature scale" and "Celsius temperature scale", the following formulas can be applied. Here, F is the value in Fahrenheit and the value in Celsius: Temperature Conversions C = 5 9 (F - 32) F = (š xc) + 3 Write a Python program that uses the above formula to convert Celsius to Fahrenheit and vice versa. We ask user to input "Enter a degree: ", and then we get a target string. We check whether the input string match the temperature form (e.g.-120, 34.23c, +345.21F, -347, ...). If the string is not matched the temperature form, we should input the data again! If it meets the temperature form, and if the temperature is in Celsius, convert to Fahrenheit and output the result. Conversely, if the temperature is Fahrenheit, convert to Celsius temperature and output it. Express the output temperature only to the second decimal place. The pattern of the temperature form is as follows: - Can have an either + or -. If this signs are omitted, the number is positive number - Numbers are integers or real numbers - The temperature is followed by C or F. There is no space between number and C or F. Both letter C and F are case insensitive - 1 -

Code:
#flag to find if entered string is in right format
tempflag = False
#while loop till user enter temperature in right format
while(tempflag==False):
#asking user to input temperature
temp = input("Enter a degree: ")
#checking the format
if (temp[-1]=='c' or temp[-1]=='C'):
#checking if temp can be converted to float
try:
float(temp[:len(temp)-1])
tempflag=True
except:
tempflag=False
if(tempflag==True):
#if satisfies above condition, convert it to fahrenheit
celcius = float(temp[:len(temp)-1])
fahrenheit = ((9 * celcius) / 5) + 32
#converting float to upto only 2 decimal places
fahrenheit1 = round(fahrenheit,2)
print(fahrenheit1,'\bF')
  
#checking the format
if (temp[-1]=='f' or temp[-1]=='F'):
#checking if temp can be converted to float
try:
float(temp[:len(temp)-1])
tempflag=True
except:
tempflag=False
#converting to celcius
if(tempflag==True):
fahrenheit = float(temp[:len(temp)-1])
celcius = (5*(fahrenheit - 32))/9
#converting float to upto only 2 decimal places
celcius1=round(celcius,2)
print(celcius1,"\bC")

Output:

Enter a degree: -123.45 Enter a degree: -123.45C - 190.21F


Enter a degree: 12 Enter a degree: 34.53 Enter a degree: 12ab Enter a degree: 345d Enter a degree: +100C 212.0F


Enter a degree: 980 208.4F


Enter a degree: 98f 36.67C


Enter a degree: 12315 Enter a degree: kl90 Enter a degree: - 12 Enter a degree: -42.34F -41.30
