My json file look likes this and I'm trying to access the element syslog in a for loop.
{
"cleanup":{
"folderpath":"/home/FBML7HR/logs",

{

"processname":"northhostsim",

}

}
}
I do it like this:
for i in data['execution']:
cmd = data['execution'][i]['test_case']['scriptname']
But I get the error saying "TypeError: list indices must be integers, not dict". I'm new to python (and json as well). Could anybody suggest where I'm going wrong ?

The Python "TypeError: list indices must be integers or slices, not dict" occurs when we use a dictionary to access a list at a specific index. To solve the error, use an integer or a slice for list indexes, e.g. my_list[0] .
The Python "TypeError: list indices must be integers or slices, not str" occurs when we use a string instead of an integer to access a list at a specific index. To solve the error, use the int() class to convert the string to an integer, e.g. my_list[int(my_str)] .
The Python "TypeError: list indices must be integers or slices, not tuple" occurs when we pass a tuple between the square brackets when accessing a list at index. To solve the error, make sure to separate nested list elements with commas and correct the index accessor.
What is a list of dictionaries in Python? We all know in Python, a list is a linear data structure that can store a collection of values in an ordered manner. And these values can be any Python object. A dictionary is also a Python object which stores the data in the key:value format.
You are looping over the values in the list referenced by data['execution'], not indices.
Just use those values (dictionaries) directly:
for i in data['execution']:
cmd = i['test_case']['scriptname']
You probably want to give that a more meaningful loop name:
for entry in data['execution']:
cmd = entry['test_case']['scriptname']
dataArray=data['execution']
for i in range(len(dataArray)):
cmd = dataArray[i]['test_case']['scriptname']
