我想将JSON格式化为特定值。我的最终目标是转化
-33.494 143.2104至
{"lat":-33.494,"lon":143.2104}
我正在将IP转换为地理位置的纬度和经度：
python3.5 -c "
import geoip2.database; reader=geoip2.database.Reader('/geoip_databases/GeoLite2-City.mmdb');
response = reader.city('1.2.3.4');
print (response.location.latitude, response.location.longitude)"
-33.494 143.2104
试图将其转换为所需的输出：
python3.5 -c "
import geoip2.database; reader=geoip2.database.Reader('/geoip_databases/GeoLite2-City.mmdb');
response = reader.city('1.2.3.4')
;a=(response.location.latitude, response.location.longitude);
b=('{"lat":' + a + '}');
c=b.replace(' ',',"lon"');
print (c)"
Traceback (most recent call last):
File "<string>", line 1, in <module>
TypeError: Can't convert 'tuple' object to str implicitly
如何完成下面的输出{“ lat”：-33.494，“ lon”：143.2104}仍然只有一个衬里？

您可以尝试制作import React, { Component } from 'react';
import {
AppRegistry,
Button,
StyleSheet,
NativeModules,
Platform,
Text,
View
} from 'react-native';
import RNPrint from 'react-native-print';
export default class RNPrintExample extends Component {
state = {
selectedPrinter: null
}
// @NOTE iOS Only
selectPrinter = async () => {
const selectedPrinter = await RNPrint.selectPrinter()
this.setState({ selectedPrinter })
}
// @NOTE iOS Only
silentPrint = async () => {
if (!this.state.selectedPrinter) {
alert('Must Select Printer First')
}
const jobName = await RNPrint.print({
printerURL: this.state.selectedPrinter.url,
html: '<h1>Silent Print</h1>'
})
}
//trying to style this HTML
async printHTML() {
await RNPrint.print({
html: '<h1>Heading 1</h1><h2>Heading 2</h2><h3>Heading 3</h3>'
})
}
async printRemotePDF() {
await RNPrint.print({ filePath: 'https://graduateland.com/api/v2/users/jesper/cv' })
}
customOptions = () => {
return (
<View>
{this.state.selectedPrinter &&
<View>
<Text>{`Selected Printer Name: ${this.state.selectedPrinter.name}`}</Text>
<Text>{`Selected Printer URI: ${this.state.selectedPrinter.url}`}</Text>
</View>
}
<Button onPress={this.selectPrinter} title="Select Printer" />
<Button onPress={this.silentPrint} title="Silent Print" />
</View>
)
}
render() {
return (
<View style={styles.container}>
{Platform.OS === 'ios' && this.customOptions()}
<Button onPress={this.printHTML} title="Print HTML" />
<Button onPress={this.printPDF} title="Print PDF" />
<Button onPress={this.printRemotePDF} title="Print Remote PDF" />
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
},
});
，然后再尝试制作json.dumps。
