SyntaxError: Expected Indented Block

[erika0193]

Below is the pasted part of my code that is coming up with the error "SyntaxError: Expected Indented Block".

def findRain(allData, target):
    '''Uses a binary search to locate rainfall amounts in mm 
    from the supplied list of dictionaries.  target is a 
    date in the 'yearmonth' value format.  The function 
    assumes that the list has been sorted by increasing 
    date. The function will raise a ValueError exception if 
    the year and month in target do not exist in allData.'''
    # You must use a binary seach and cannot use any built- 
    in searches.
    low = 0
    high = len(allData) - 1
    while low <= high:
        <indent> mid = (low + high) // 2
        print (allData[mid]["yearmonth"])
        print (target)
        if target < allData[mid]["yearmonth"]:
            <indent><indent>high = mid - 1
        <indent> elif target > allData[mid]["yearmonth"]:
            <indent><indent> low = mid + 1
        <indent> else:           
            <indent><indent> return (allData[mid]["rain"])   
    <indent>raise ValueError("Target not found")

Edit: When it posts the indents do not show up; so each "<indent>" written indicates a "tab".

You have begun a multi-line string literal for your docstring (starting with ''') but left out the closing '''. At the end of line 9, add that ''', or insert a line afterward consisting of just the ''' and nothing else. (My preference is to indent it 4 spaces to line up with the text above, but that's optional.)

I can't tell if there are other problems, since the code hasn't pasted correctly. Those "<insert>" tokens look like some sort of markup.

Putting in an extra space or leaving one out where it is needed will surely generate an error message . Some common causes of this error include:

• Forgetting to indent the statements within a compound statement
• Forgetting to indent the statements of a user-defined function.

The error message IndentationError: expected an indented block would seem to indicate that you have an indentation error. It is probably caused by a mix of tabs and spaces. The indentation can be any consistent white space . It is recommended to use 4 spaces for indentation in Python, tabulation or a different number of spaces may work, but it is also known to cause trouble at times. Tabs are a bad idea because they may create different amount if spacing in different editors .
