In Python, **"typeerror: not all arguments converted during string formatting"** primarily occurs when:
1. There is no format specifier.
2. The format specifiers and the number of values are different.
3. Two format specifiers are mixed.

# Code 

## 1. No format specifier with the string interpolation operator


# Since `x` is a string, the `%` operator is treated as a string
# interpolation operator. The error occurs because no format specifier
# is provided.
x = "11"
if(x % 2):
  print("x is odd")

x = "11"
# This tells the compiler that % is used as the modulus operator
if(int(x) % 2):
  print("x is odd")

## 2. Unequal format specifiers and  values

fav_food = "pizza"
fav_show = "Friends"
fav_day = "Saturday"
fav_month = "June"
print("I like to eat %s while watching %s." % (fav_day, fav_food, fav_month, fav_show))

fav_food = "pizza"
fav_show = "Friends"
fav_day = "Saturday"
fav_month = "June"
print("I like to eat %s while watching %s." % (fav_food, fav_show))

fav_food = "pizza"
fav_show = "Friends"
print ("I like to eat '{0}' while watching '{1}'." % fav_food, fav_show)

fav_food = "pizza"
fav_show = "Friends"
print ("I like to eat %s while watching %s." % (fav_food, fav_show))


fav_food = "pizza"
fav_show = "Friends"
print ("I like to eat {0} while watching {1}.".format(fav_food, fav_show))
