The conversion algorithm is as follows: (C means Celsius, F means Fahrenheit)
C = ( F - 32 ) / 1.8
F = C * 1.8 + 32
Requirements are as follows
(1) The input and output degrees Celsius can end with a capital or uppercase letter C, and the temperature can be an integer or a decimal, for example: 12.34C means 12.34 degrees Celsius;
(2) The input and output Fahrenheit can end with a capital or uppercase letter F, and the temperature can be an integer or a decimal, for example: 87.65F means 87.65 degrees Fahrenheit;
(3) The output retains two decimal places. When the input format is incorrect, the output prompts: Input format error;
(4) When using input() to obtain test case input, do not add a prompt string.
tempstr=input()
if tempstr[-1] in ['F','f']:
c=(eval(TempStr[0:-1])-32)/1.8
print("{:.2f}C".format(c))
elif tempstr[-1] in ['C','c']:
f=eval(tempstr[0:-1])*1.8+32
print("{:.2f}F".format(f))
else : print("输入格式错误")
