Python inserts a string in the middle of the list

>>> a=['The Weak ! ','No Sendagaya! ','wryyyy! ']>>> a[0:0]='Euler! ' #Direct insertion causes character splitting>>>a['Europe','Pull','! ','The Weak ! ','No Sendagaya! ','wryyyy! '] >>> a[0:3]=["Euler! "]#just wrap the string in the list .>>>a['Euler! ','The Weak ! ','No Sendagaya! ','wryyyy! ']>>> A.insert (0,"high! ")#In fact, insert is also OK>>>a['high! ','Euler! ','The Weak ! ','No Sendagaya! ','wryyyy! ']
