How do you write this question in python?

class solution(object):

def twosum(self, nums, target):

type nums: list[int]

type target: int

rtype: list[int]

length = len(nums);

differdict = {} Dictionary for i in range(length):

num = nums[i];

item = ;Check whether the current value is already in the difference --index dictionary if item == none: If not, the target value and the current value are used as key, and the index is used as value

differdict[target - num] = i;

else: If it exists, return directly.

return [item,i];

The maximum value is 99, and the maximum value will appear when executed 98 times, the algorithm is not critical, the key is that the computer is trying to calculate, knowing that the maximum value has actually completed a minimum calculation when it appears, all the times that need to be calculated minus 1 or the number of times directly from -1 are feasible, as follows:

The question asks what is the maximum value of n after any execution of n=(n+1)%100, where the initial value of n is 1.

This is actually very simple, % in python is to find the remainder, the initial value of 1 means that n is int (integer), and the maximum positive integer less than 100 is 99, so the maximum value of n is 99.

A python practice problem is a type of programming exercise designed to help learners better understand the basic concepts and features of the Python language. Here are some examples of python practice questions:1

Create a list of numbers with 10 numbers, and then use the for loop to print them out: numbers = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]for num in numbers: print(num)2

Write a function that accepts a string as an argument and returns the length of the string: def string length(str): return len(str)3

Write a function that takes a list of numbers as a parameter and returns the sum of all numbers in that list: def list sum(nums): total = 0 for num in nums:

total +=num return total, I hope this service can help you <>

Summary. If you draw 6 subgraphs with 3 rows and 2 columns, the subgraph number corresponding to the 5th subgraph area is 3. Therefore, to create a subplot area of a vertical bar chart, you can use the following matplotlib:

pythonimport as pltfig, axs = , ncols=2, figsize=(10,10))axs[2, 0].bar(x, height) where axs[2, 0] represents the subgraph of row 3 and column 1, and the vertical bar chart is drawn by calling the bar() function. x and height are the data for the bar chart and need to be populated according to the actual situation.

The figsize parameter specifies the size of the entire drawing, which can be adjusted as needed. Finally, use functions to display graphs.

Help me do it, let me know the answer.

If you draw 6 subgraphs with 3 rows and 2 columns, the subgraph number corresponding to the 5th subgraph area is 3. Therefore, to create a subgraph region of a vertical bar chart, you can use the following matplotlib code: pythonimport as pltfig, axs = , ncols=2, figsize=(10,10))axs[2, 0].

bar(x, height) where axs[2, 0] represents the subgraph of row 3 and column 1, and the vertical bar is drawn by calling the bar() function. x and height are the data for the bar chart and need to be populated according to the actual situation. The figsize parameter specifies the size of the entire drawing, which can be adjusted as needed.

Finally, use functions to display graphs.

So what to choose? The second a

What about the other two? b c

In the first question, enter two numbers, do division, and return a float result, keeping two decimal places:

The input value is the output.

** Below(Programming is not easy, if approved).

Dictionaries store information.

dict = School of Accountancy": Faculty of Plumbing":

The total number of teachers in each faculty is calculated.

total_teachers =

Output the name of the academy and the total number of students.

for college, total in total_:

print(college, "Total number of teachers:",total) Find out the colleges with the youngest number of teachers.

min_college = min(total_teachers, key=total_

print("The college with the lowest number of teachers:",min_college)Running Result:

Summary. Using functions, you can split strings according to a specified pattern of regular expressions. Here, we use patterns.

to match one or more arbitrary characters. Follow the given **'.'), the result is a list of split substrings.

According to the pattern. +, which matches each non-empty substring in the string and then splits it. In this example, the following substring is matched:

alpha’‘beta’‘gamma’‘delta’

Using the function, you can split the string according to the regular expression pattern specified by the knowledge of the deficiency. Here, we use patterns. to match one or more arbitrary characters.

Follow the given **'.'), the result is a list of substrings that have been split up. According to the pattern. +, which matches each non-empty substring in the string and then splits it. In this example, the following substrings are matched: 'alpha', 'beta', 'gamma', 'delta'

Therefore, the end result is ['alpha', beta', gamma', delta']
