python - Convert string with engineer prefix to float -


I have a string like '102.3k' I replace this string with an engineer Prefix marking in a float number

Allowed prefixes 

  posPrefixes = ['k', 'm', 'j', 't', 'p' Negroprefixes = '' '' '' '' '' '' '' '' '' '' '' '' '' '' / P>  p> μ means 10 ^ -6  
 I think I should use regex to do this, but I have a lot of experience with regex.  
 Edit: Ideally the solution should also be enabled to convert any wire '102.3' (without the prefix) should also be converted to float   
 
 
 Try this, no regex required:  
  pos_postfixes = ['k', 'm', 'j ['M', 'μ', 'n', 'p', 'f', 'a', '', 'p', 'p', 'e', ​​'z', 'y'] neg_postfixes = Num_postfix = n [-1] if pos_postfixes in num_postfix: num = float n [: - 1]) number * = 10 ** ((pos_p Num_postfixes: num = float (n [: - 1] ) Num * = 10 ** (- (neg_postfixes.index (num_postfix) +1) * 3) Other Th ostfixes.index (num_postfix) +1) * 3) elif num_postfix: Num = float (n) print (num)  
 
 The point of note is that in Python, the comparison of therm The names of at least variable names are more common to use, PEP-8:

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
