Hello Guys, I'm a newbie in Python and now I have an array with days of weeks as below:
week_days = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']
mon, tue, wed = week_days
print(mon)
print(tue)
print(wed)
I want to assign value items to variables but I don't want to loop file. But I got an error ValueError: too many values to unpack (expected 3)
Traceback (most recent call last):
File "main.py", line 2, in <module>
mon, tue, wed = week_days
ValueError: too many values to unpack (expected 3)
How can I get only three first items into three variables?
Have 2 answer(s) found.

You can list all variables equal with items of an array. You can see the example below:
week_days = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday'] mon, tue, wed, thur, fri, sta, sun = week_days print(mon) print(tue) print(wed) -

You can use
*start symbol for variable fourth to end of the array.week_days = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday'] mon, tue, wed, *thur = week_days print(mon) # output Monday print(tue) # output Tuesday print(wed) # output WednesdayI hope it helpful for you.
