}how to verify json format is valid
I use Gson class in order to convert a
Json object into a java object.
If it works without any error, it means that it is a valid json format...
import com.google.gson.Gson;
public class JSONUtils {
Gson gson = new Gson();
public boolean isJSONValid(String jsonInString) {
try {
gson.fromJson(jsonInString, Object.class);
return true;
} catch(com.google.gson.JsonSyntaxException e) {
return false;
}
}
}JSON validate
**Output:** ['Finland', 'Florida', 'france']JSON validate
S=pd.Series(['Finland','Colombia','Florida','Japan','Puerto Rico','Russia','france'])
[itm[0] for itm in S.str.findall('^[Ff].*') if len(itm)>0]JSON validate
import numpy as np
df['first_five_Letter']=df['Country (region)'].str.extract(r'(^w{5})')
df.head()JSON validate
# Get countries starting with letter P
S=pd.Series(['Finland','Colombia','Florida','Japan','Puerto Rico','Russia','france'])
S[S.str.match(r'(^P.*)')==True]Copyright © 2021 Codeinu
