Function Name:
locals
Function Signature:
locals()
Function Overview:
- The locals() built-in function returns the local symbol table of a function as a dictionary.
- Unlike globals(), the dictionary is a copy of the original symbol table maintained by python for a function.
- Hence any modifications made to the dictionary returned by locals() method does not reflect in the actual program execution.
Example 1:
|
# Function defined at module level def F1(val): x = val
# Get the local symbol table for function F1 symTable_Local = locals()
# Print the symbol table print("Local symbol table==>{}".format(symTable_Local))
# Call function F1 F1(10) |
Output:
|
Local symbol table==>{'x': 10, 'val': 10} |
Example 2:
|
# Function defined at module level def G1(value): y = value
# Get the local symbol table for function F1 symTable_Local = locals()
# Print the symbol table print("Local symbol table==>{}".format(symTable_Local))
# Modify the symbol table symTable_Local["y"] = 20
# print the value of y print(y)
# Call function G1 G1(10) |
Output:
|
Local symbol table==>{'y': 10, 'value': 10} 10 |
