I am having a for-loop which takes rows within a pandas dataframe df_drinks and uses them as parameters to call another function order(). order() is imported from the module restaurant.py.
Together with the row in df_drinks, I want to submit a comment to the order(), which is specified outside the for-loop.
from restaurant import order
statement = "Lets order"
df_drinks = ["1 drink", "2 drink"] # simplified, 1 item per row, many columns
for index, row in df_drinks.iterrows():
print ("%s, %s" % (statement, row))
item = row
response = order(statement, item)
...
The module looks like this:
# restaurant.py
def order(statement, item):
listen(statement)
statement = "order received"
ready_drinks = prepare(item)
...
return ready_drinks
For the first run/row everything is fine since a print yields:
Lets order 1 drink
However, for the second run/row, print yields:
order received 2 drinks instead of Lets order 2 drinks.
I understand that I have the same variable name statement for two different things. Still, I am confused since order() in restaurant.py does only return ready_drinks and not statement.
How to correctly assign local variables to a for-loop in python?
statement = "order received" is a local variable and statement = "Lets order" is a Global variable. You are no where overriding the value in the for loop. May be below code helps you
df_drinks = ["1 drink", "2 drink"] # simplified, 1 item per row, many columns
for row in df_drinks:
statement = "Lets order"
print ("%s, %s" % (statement, row))
item = row
ready_drinks,statement = order(statement, item)
print ("%s, %s" % (statement, row))
def order(statement, item):
listen(statement)
statement = "order received"
ready_drinks = prepare(item)
...
return ready_drinks,statement
