typeerror

问题 I've been getting the error: TypeError: float() argument must be a string or a number, not 'method'. Below is my snippet of code. I've checked other posts like this one: TypeError: float() argument must be a string or a number, not 'function' – Python/Sklearn but can't seem to get to the root cause of the error. Is python saying that my variables (y, x1, x2 etc.) are 'methods' which is why I'm receiving the error? If so, does anyone know how I can resolve this? Thanks in advance to anyone

问题 this problem appears only in joomla - im trying to use the contentflow plugin with my joomla site this is the plugin site - http://www.jacksasylum.eu/ContentFlow/ this is my site - http://2-dweb.com/RND/ as you can see it doesnt work - it just stays on the loading phase forever upon closer inspection i can see that there is a problem with this code: if (this.content.nodeName == "IMG") { CFobj._imagesToLoad++; var foobar = function () { CFobj._imagesToLoad--; this.image = this.content; this

问题 x = 4 y = 5 a = 3(x + y) print(a) I keep trying to solve that. I've even tried this. x = input("Enter value for x:") Enter value for x:4 y = input("Enter value for y:") Enter value for y:5 a = 3 x + y What am I doing wrong? 回答1: I suspect that you want 3(x + y) to be acted upon as that would be in algebra, that is to multiply the result of x + y by 3. For that you need to use the multiplication operator * : a = 3 * (x + y) Python will take the parentheses after a token as a function call as

问题 This is the code where I use Animated.text only here. It was working but when I installed react-native-render-html library after that this error comes. However, I have uninstalled that library but still this error comes. return ( <View style={styles.tabBar}> {props.navigationState.routes.map((route, i) => { const color = Animated.color( Animated.round( Animated.interpolate(props.position, { inputRange, outputRange: inputRange.map(inputIndex => inputIndex === i ? 255 : 0 ), }) ), 0, 0 );

问题 So beginner here at Python, using it for economic research. I am currently trying to run code to find the roots of a CES Function using the Newton-Ralphson Method (https://quanteconpy.readthedocs.io/en/latest/optimize/root_finding.html). However, I am running into an error here where it says "TypeError: unsupported operand type(s) for -: 'CPUDispatcher' and 'int'". I have no clue what this means (I am using Spyder for Python 3.8) so any help would be much appreciated. My code is attached

问题 I'm a beginner at Python just getting to grips with classes. I'm sure it's probably something very basic, but why does this code: class Television(): def __init__(self): print('Welcome your TV.') self.volume = 10 self.channel = 1 def channel(self, channel): self.channel = input('Pick a channel: ') print('You are on channel ' + self.channel) def volume_up(self, amount): self.amount = ('Increase the volume by: ') self.volume += self.amount print('The volume is now ' + self.volume) def volume
