print(' '.join(chain))

Ending up with the following error:

chain.append(np.random.choice(word_dict[chain - 1]))
TypeError: unsupported operand type(s) for -: 'list'
and 'int'

According to your logic, I think this is what you are looking for:

chain.append(np.random.choice(word_dict[chain[-1]]))

When working in Python, you might have used concatenation for joining two values. The concatenation operator “+” is used for this. But while doing so, a common error that is encountered is “TypeError unsupported operand type(s) for + 'int' and 'str'”. This happens when the two or more values that you are trying to add are not of the same data type.,In this article, we will look at the different scenarios where you might encounter this error. Then we will find ways to fix it.,You encounter this error as you are trying to add an integer and a string. This is not possible. You have to change this line print(intlist.pop(2) + " Second Element has Removed from List"). Change it using any of these processes described below:,indentationerror: unindent does not match any outer indentation level in Python

Let us consider the following piece of code:

# Python program to add two values
val1 = 10
val2 = '12'

# Add two values
out = val1 + val2
print('Sum of two values: ', out)

Output:

out = val1 + val2
TypeError: unsupported operand type(s) for +: 'int'
and 'str'

In the above example you are trying to add an integer and a string. This is not possible.

val1 = 10 # # Declared as Integer
val2 = '12'
# # Declared as string

5._

# Enter three integer value to create list
int1 = int(input("Enter First Integer: "))
int2 = int(input("Enter Second Integer:"))
int3 = int(input("Enter Third Integer: "))

# Add all interger value in list
intlist = [int1, int2, int3]

# Print Integer List
print('List Created: ', intlist)
print("Remove Second Element from List")
print(intlist.pop(2) + " Second Element has Removed from List")
print("New List: " + str(intlist))

After entering all the values of the variables int1, int2 and int3, the code returns this:

TypeError: unsupported operand type(s) for +: 'int'
and 'str'

Also, in your if make ( ) around your addition, and only in the end divide by /2.0 (without the .0 you receive a rounded down integer). Because Python respects precedence of operators and without the ( ) you would not make an average.,Also, your median = 5.5 is useless. And in your if make sure to give it the right name. median instead of medium.,ResourcesArrow Chevron Down Filled IconProjectsNewInterview ChallengesDocsCheatsheetsArticlesVideosBlogCareer Center,Can someone please explain why this doesn’t work. It looks similar to others but I am sure it is something stupid I am missing. The error I get is “Oops, try again. median([4, 5, 5, 4]) resulted in an error: unsupported operand type(s) for -: ‘list’ and ‘int’”

  def median(numbers):
     median = 5.5
  sort = sorted(numbers)
  if len(sort) % 2 == 0:
     medium = sort[len(sort) / 2] + sort[len(sort - 1) / 2] / 2
  else:
     median = sort[len(sort) / 2]
  return median

Create two separate data type variables in python, say an integer value and a string value. Using the plus “+” operator to concatenate these values. This error TypeError: unsupported operand type(s) for +: ‘int’ and ‘str’ will be seen due to the mismatch between the data types of the values.,The TypeError: unsupported operand type(s) for +: ‘int’ and ‘str’ error occurs when an integer value is added with a string that could contain a valid integer value. Python does not support auto casting. You can add an integer number with a different number. You can’t add an integer with a string in Python. The Error TypeError: unsupported operand type(s) for +: ‘int’ and ‘str’ will be thrown if an integer value is added to the python string.,The objects other than numbers can not use for arithmetic operation such as addition, subtraction etc. If you try to add a number to a string containing a number, the error TypeError: unsupported operand type(s) for +: ‘int’ and ‘str’ will be shown. The string should be converted to an integer before it is added to another number.,Through this article, we can see what this error TypeError: unsupported operand type(s) for +: ‘int’ and ‘str’ is, how this error can be solved. This type error is a mismatch of the concatenation of two different data type variables. The error would be thrown as like below.

Through this article, we can see what this error TypeError: unsupported operand type(s) for +: ‘int’ and ‘str’ is, how this error can be solved. This type error is a mismatch of the concatenation of two different data type variables. The error would be thrown as like below.

Traceback (most recent call last):
File "/Users/python/Desktop/test.py", line 3, in <module>
   print x + y
   TypeError: unsupported operand type(s) for +: 'int' and 'str'
   [Finished in 0.1s with exit code 1]

The code below indicates the concatenation of two separate data type values. The value of x is the integer of y. The value of y is a string.

x = 5
y = "Yawin Tutor"
print x + y

Output

Traceback (most recent call last):
File "/Users/python/Desktop/test.py", line 3, in <module>
   print x + y
   TypeError: unsupported operand type(s) for +: 'int' and 'str'
   [Finished in 0.1s with exit code 1]

Python cannot add a number and a string. Either both the variable to be converted to a number or a string. If the variables are changed to a number, the mathematical addition operation will be done. The error “TypeError: unsupported operand type(s) for +: ‘int’ and ‘str'” will be resolved.

x = 5
y = 8
print x + y

In the above program, The variables are converted to a string. Python interpreter concatenate two variables. the variable value is joined together. The example below shows the result of addition of two strings.

x = '5'
y = '8'
print x + y
