I was just trying out the exec() function in Python when I encountered an issue with my code. Here's some sample code to illustrate my issue:
I have a simple function that just executes code that is given to the function:
def executeCode(pythonCode):
exec(pythonCode)
I have 2 variables that contain code with similar functions:
pythonCode1 = """
import pandas as pd
# Create a DataFrame from a dictionary
data = {'Name': ['John', 'Emily', 'Mike', 'Lisa'],
'Age': [25, 28, 30, 27],
'City': ['New York', 'London', 'Paris', 'Tokyo']}
def f(data):
print(pd.DataFrame(data))
# Display the DataFrame
f(data)
"""
pythonCode2 = """
import pandas as pd
# Create a DataFrame from a dictionary
data = {'Name': ['John', 'Emily', 'Mike', 'Lisa'],
'Age': [25, 28, 30, 27],
'City': ['New York', 'London', 'Paris', 'Tokyo']}
df = pd.DataFrame(data)
# Display the DataFrame
print(df)
"""
When I run executeCode with the 2 chunks of code, I get 2 different results.
Running executeCode(pythonCode1) gives an error:
Traceback (most recent call last):
File "C:\pythonEnvironment\vite-project\test.py", line 38, in <module>
executeCode(pythonCode1)
File "C:\pythonEnvironment\vite-project\test.py", line 35, in executeCode
exec(pythonCode)
File "<string>", line 13, in <module>
File "<string>", line 10, in f
NameError: name 'pd' is not defined. Did you mean: 'id'?
While running executeCode(pythonCode2) returns the correct result:
Name Age City
0 John 25 New York
1 Emily 28 London
2 Mike 30 Paris
3 Lisa 27 Tokyo
Could someone explain why this happens? I think its related to how the scopes of the functions work, since pythonCode2 does not contain a function and it works. I've also ensured that pandas is installed.
