Python [33] asked daily

ask:

[1] basic questions: a weight transducer design, the input to "g" after the return of the number of units in terms of "kg" Results

[2] basis title: Design of a rectification function of the hypotenuse, such as right-angle side length of 3 and 4, respectively, as output: The right triangle third side's length is 5.0

[Title] increase: Triangle print out (printed out to achieve a corresponding number of rows as the digital keyboard input, such as input 10, print the line 10)

answer:

[1] basic questions: a weight transducer design, the input to "g" after the return of the number of units in terms of "kg" Results

method 1:

def weight_conversion(weight, option):
    if option == '1':
        return str(weight * 1000) + 'g'
    elif option == '2':
        return str(weight / 1000) + 'kg'
    else:
        print('没有此选项')
​
​
if __name__ == '__main__':
    option = input('1. kg to g\n2. g to kg\n请选择:' ) 
    Weight = int (INPUT ( ' Enter weight: ' ))
     Print (weight_conversion (weight, Option))

 

Method 2:

int = WG (INPUT ( " Please enter the base in grams (G) !!! \ n- " )) 
WKG = WG / 1000 Print ( " into kilogram:% F (kg) " % WKG)

 

 

[2] basis title: Design of a rectification function of the hypotenuse, such as right-angle side length of 3 and 4, respectively, as output: The right triangle third side's length is 5.0

method 1:

Import Math 
DEF hypotenuse (A, B):
     '' ' 
    : A param: cathetus 
    : param b: cathetus 
    : return: hypotenuse 
    ' '' 
    return Math.sqrt (A ** 2 ** 2 + B ) 
IF  the __name__ == ' __main__ ' : 
    A = int (iNPUT ( " Please enter a right-angle side: " )) 
    B = int (iNPUT ( " Please enter the other angle side: " ))
     Print ( " of The right Triangle Side length apos IS THIRD " , hypotenuse (A, B))

 

Method 2:

Import Math
 Print ( " .. " * 16 ) 
X = int (INPUT ( " Please enter the length of a side edge of the right triangle: \ n- " )) 
Y = int (INPUT ( " Please enter the right-angle side of the other side length: \ n- " )) 
Z = Math.sqrt (Y * X * X + Y)
 Print ( " .. " * 16 )
 Print ( " hypotenuse length: {} " .format (Z ))

 

 

[Title] increase: Triangle print out (printed out to achieve a corresponding number of rows as the digital keyboard input, such as input 10, print the line 10)

method 1:

 

int = Lines (INPUT ( " Please enter the number of printed lines: " )) 
out_list, process_list = [. 1], [. 1 ]
 IF Lines. 1 == :
     Print ( ' {} ' .format ( '  ' .join (List (Map (STR, out_list)))))
 the else :
     for J in Range (lines):   # of rows 
        Print ( ' {} ' .format ( '  ' .join (List (Map (STR, out_list)))))
         for I in Range (. 1, J + 2):   # next line number of each line 
            if i > len(out_list) - 1:
                process_list.append(1)
            else:
                process_list.append(out_list[i - 1] + out_list[i])
        out_list = process_list[:]
        process_list = [1]

 

Method 2:

import numpy as np
​
​
def get_triangle():
    row = np.array([1])
    yield row
    margin_array = np.array([0])
    while True:
        next_row = np.concatenate((margin_array, row)) + np.concatenate((row, margin_array))
        yield list(next_row)
        row = next_row
​
​
triangle = get_triangle()
for i in range(10):
    print(f"row {i+1}: ", triangle.__next__())
